Concrete, particularly the reinforced variety, is the most versatile of all construction materials, and most of the hydraulic cement produced worldwide is portland cement or similar cements that have portland cement as a basis, such as blended cements and masonry cements. Cement typically makes up less than 15 percent of the concrete mix; most of the rest is aggregates. Not counting the weight of reinforcing media, 1 ton of cement will typically yield about 8 tons of concrete.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geosciences Institute","publisherLocation":"Alexandria, VA","usgsCitation":"van Oss, H.G., 2012, Mineral resource of the month: hydraulic cement: Earth, v. 2012, no.

Primary stratigraphic units of focus are the Lower Ordovician El Paso and Upper Ordovician Montoya Groups. These groups preserve breccias formed by collapse of a paleocave system. Precambrian and Silurian units are discussed in the context of breccia clast composition and relative timing of breccia emplacement. Specific attention is paid to the juxtaposition of the top-Sauk second-order supersequence unconformity between the El Paso and Montoya Groups and its relationship to breccias above and below it. The unconformity represents a 10-m.y. exposure event that separates Upper and Lower Ordovician carbonates. The top-Sauk exposure has been previously documented as a significant karst horizon across much of North America.</p><p>The breccias of the SFM were previously described as the result of collapsed paleocaves that formed during subaerial exposure related to the Sauk-Tippecanoe unconformity.

However, it remains highly debated as to whether adakites form by slab melting, by partial melting of the lower continental crust, or by fractional crystallization of normal arc magmas. Here, we show that to form adakitic signature, partial melting of a subducting oceanic slab would require high pressure at depths of &gt;50 km, whereas partial melting of the lower continental crust would require the presence of plagioclase and thus shallower depths and additional water. These two types of adakites can be discriminated using geochemical indexes. Compiled data show that adakites from circum-Pacific regions, which have close affinity to subduction of young hot oceanic plate, can be clearly discriminated from adakites from the Dabie Mountains and the Tibetan Plateau, which have been attributed to partial melting of continental crust, in Sr/Y-versus-La/Yb diagram. Given that oceanic crust has copper concentrations about two times higher than those in the continental crust, whereas the high oxygen fugacity in the subduction environment promotes the release of copper during partial melting, slab melting provides the most efficient mechanism to concentrate copper and gold; slab melts would be more than two times greater in copper (and also gold) concentrations than lower continental crust melts and normal arc magmas. Thus, identification of slab melt adakites is important for predicting exploration targets for copper- and gold-porphyry ore deposits. This explains the close association of ridge subduction with large porphyry copper deposits because ridge subduction is the most favorable place for slab melting.</span></p>","language":"English","publisher":"The University of Chicago Press Books","doi":"10.1086/662736","issn":"00221376","usgsCitation":"Sun, W., Ling, M., Chung, S., Ding, X., Yang, X.,

The ASSM is part of the Monte Amiata Hg district, Southern Tuscany, Italy, which was one of the world’s largest Hg districts. Concentrations of Hg and methyl-Hg were determined in mine-waste calcine (retorted ore), sediment, water, soil, and freshwater fish collected from the ASSM and the downstream Paglia River. Concentrations of Hg in calcine samples ranged from 25 to 1500 μg/g, all of which exceeded the industrial soil contamination level for Hg of 5 μg/g used in Italy. Stream and lake sediment samples collected downstream from the ASSM ranged in Hg concentration from 0.26 to 15 μg/g, of which more than 50% exceeded the probable effect concentration for Hg of 1.06 μg/g, the concentration above which harmful effects are likely to be observed in sediment-dwelling organisms. Stream and lake sediment methyl-Hg concentrations showed a significant correlation with TOC indicating considerable methylation and potential bioavailability of Hg. Stream water contained Hg as high as 1400 ng/L, but only one water sample exceeded the 1000 ng/L drinking water Hg standard used in Italy. Concentrations of Hg were elevated in freshwater fish muscle samples and ranged from 0.16 to 1.2 μg/g (wet weight), averaged 0.84 μg/g, and 96% of these exceeded the 0.3 μg/g (methyl-Hg, wet weight) USEPA fish muscle standard recommended to protect human health. Analysis of fish muscle for methyl-Hg confirmed that > 90% of the Hg in these fish is methyl-Hg.

We fitted 13 adult females with Geographic Positioning System (GPS) radio-collars and monitored them between 2001 and 2004. We examined patterns of habitat selection by grizzly bears relative to topographical attributes and 3 potential surrogates of food availability: land-cover class, vegetation biomass or quality (as measured by the Normalized Difference Vegetation Index), and selection value for prey species themselves (moose [Alces alces], elk [Cervus elaphus], woodland caribou [Rangifer tarandus]. Stone's sheep [Ovis dalli stonei]). Although vegetation biomass and quality, and selection values for prey were important in seasonal selection by some individual bears, land-cover class, elevation, aspect, and vegetation diversity most influenced patterns of habitat selection across grizzly bears, which rely on availability of plant foods and encounters with ungulate prey. Grizzly bears as a group avoided conifer stands and areas of low vegetation diversity, and selected for burned land-cover classes and high vegetation diversity across seasons. They also selected mid elevations from what was available within seasonal ranges. Quantifying relative use of different attributes helped place selection patterns within the context of the landscape. Grizzly bears used higher elevations (1,595 ± 31 m SE) in spring and lower elevations (1,436 ± 27 m) in fall; the range of average elevations used among individuals was highest (500 m) during the summer. During all seasons, grizzly bears most frequented aspects with high solar gain. Use was distributed across 10 land-cover classes and depended on season. Management and conservation actions must maintain a diverse habitat matrix distributed across a large elevational gradient to ensure persistence of grizzly bears as levels of human access increase in the northern Rocky Mountains.</p>","language":"English","publisher":"The Wildlife Society","doi":"10.1002/jwmg.235","issn":"0022541X","usgsCitation":"Milakovic, B., Parker, K., Gustine, D., Lay, R., Walker, A., and Gillingham, M., 2012, Seasonal habitat use and selection by grizzly bears in Northern British Columbia: Journal of Wildlife Management, v. 76, no. 1, p. 170-180, https://doi.org/10.1002/jwmg.235.","productDescription":"11 p.","startPage":"170","endPage":"180","costCenters":[],"links":[{"id":474832,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/jwmg.235","text":"Publisher Index Page"},{"id":242975,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215192,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.235"}],"country":"Canada","otherGeospatial":"Northern British Columbia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.05859375,\n              59.88893689676585\n            ],\n            [\n              -139.04296875,\n              60.1524422143808\n            ],\n            [\n              -134.47265625,\n              56.36525013685606\n            ],\n            [\n              -130.60546875,\n              54.16243396806779\n            ],\n            [\n              -120.32226562500001,\n              53.85252660044951\n            ],\n            [\n              -120.05859375,\n              59.88893689676585\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"76","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-09-21","publicationStatus":"PW","scienceBaseUri":"505b88aee4b08c986b316ad9","contributors":{"authors":[{"text":"Milakovic, B.","contributorId":100618,"corporation":false,"usgs":true,"family":"Milakovic","given":"B.","email":"","affiliations":[],"preferred":false,"id":450215,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Parker, K.L.","contributorId":102280,"corporation":false,"usgs":true,"family":"Parker","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":450216,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gustine, D.D.","contributorId":82536,"corporation":false,"usgs":true,"family":"Gustine","given":"D.D.","email":"","affiliations":[],"preferred":false,"id":450213,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lay, R.J.","contributorId":49986,"corporation":false,"usgs":true,"family":"Lay","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":450211,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Walker, A.B.D.","contributorId":84169,"corporation":false,"usgs":true,"family":"Walker","given":"A.B.D.","email":"","affiliations":[],"preferred":false,"id":450214,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gillingham, M.P.","contributorId":76555,"corporation":false,"usgs":true,"family":"Gillingham","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":450212,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The hypotheses were tested that (i) age and growth of lake sturgeon in the Namakan Reservoir would differ by sex and reproductive stage of maturity, and (ii) that the relative strength of year-classes of lake sturgeon in the reservoir would be affected by environmental variables. To quantify age, growth and mortality of the population, existing data was used from a multi-agency database containing information on all lake sturgeon sampled in the reservoir from 2004 to 2009. Lake sturgeon were sampled in the Minnesota and Ontario waters of the Namakan Reservoir using multi-filament gillnets 1.8&nbsp;m high and 30&ndash;100&nbsp;m long and varying in mesh size from 178 to 356&nbsp;mm stretch. Reproductive structure of the lake sturgeon was assessed only during spring 2008 and 2009 using plasma testosterone and estradiol-17&beta; concentrations. Ages of lake sturgeon &gt;75&nbsp;cm ranged from 9 to 86&nbsp;years (n&nbsp;=&nbsp;533, mean&nbsp;=&nbsp;36&nbsp;years). A catch-curve analysis using the 1981&ndash;1953&nbsp;year classes estimated total annual mortality of adults to be 4.8% and annual survival as 95.2%. Using logistic regression analysis, it was found that total annual precipitation was positively associated with lake sturgeon year-class strength in the Namakan Reservoir. A 10&nbsp;cm increase in total annual precipitation was associated with at least a 39% increase in the odds of occurrence of a strong year class of lake sturgeon in the reservoir. Plasma steroid analysis revealed a sex ratio of 2.4 females: 1 male and, on average, 10% of female and 30% of male lake sturgeon were reproductively mature each year (i.e. potential spawners). Moreover, there was evidence based on re-captured male fish of both periodic and annual spawning, as well as the ability of males to rapidly undergo gonadal maturation prior to spawning. Knowledge of lake sturgeon reproductive structure and factors influencing recruitment success contribute to the widespread conservation efforts for this threatened species.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1439-0426.2011.01927.x","usgsCitation":"Shaw, S.L., Chipps, S.R., Windels, S.K., Webb, M., McLeod, D.T., and Willis, D., 2012, Lake sturgeon population attributes and reproductive structure in the Namakan Reservoir, Minnesota and Ontario: Journal of Applied Ichthyology, v. 28, no. 2, p. 168-175, https://doi.org/10.1111/j.1439-0426.2011.01927.x.","productDescription":"8 p.","startPage":"168","endPage":"175","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-031252","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":323706,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Minnesota, Ontario","otherGeospatial":"Namakan Reservoir","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.44696044921875,\n              48.25576986959547\n            ],\n            [\n              -93.44696044921875,\n              48.69821216562637\n            ],\n            [\n              -92.35931396484374,\n              48.69821216562637\n            ],\n            [\n              -92.35931396484374,\n              48.25576986959547\n            ],\n            [\n              -93.44696044921875,\n              48.25576986959547\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"28","issue":"2","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2012-02-06","publicationStatus":"PW","scienceBaseUri":"57627c34e4b07657d19a69fe","contributors":{"authors":[{"text":"Shaw, S.

These photosymbiotic foraminifera lived in warm, oligotrophic, shallow waters within the photic zone. Such Paleogene families as the nummulitids, alveolinids, and orthophragminids rose to prominence in the late Paleocene, thrived in the early and middle Eocene, and declined in the late Eocene and Oligocene. Diversity data from these three families were studied to understand better the controls on the rise of Paleogene LBFs. Analyzed data included total diversity (total number of species per biozone), number of first occurrences per biozone, and number of last occurrences per biozone. Results indicate that there were four intervals of increased total diversity, increased first occurrence, and increased last occurrence for all three families studied. These four intervals follow closely after important climatic events within the Paleogene: the mid-Paleocene biotic event (MPBE), the Paleocene–Eocene thermal maximum (PETM, a hyperthermal event), the early Eocene Climatic Optimum (EECO) and the middle Eocene Climatic Optimum (MECO). The shallow marine biotic community, on a global scale, reacted to such climatic warming events as the MPBE, PETM, EECO, and MECO, based on these diversity trends. Our data also show a pattern of an increase in the number of last occurrences followed by an increase in the number of first occurrences, which suggests that the overall increase in species diversity is due to faunal turnover, as has been interpreted for the large benthic foraminiferal turnover that occurred at the PETM.</span></p>","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/palo.2010.p10-109r","usgsCitation":"Whidden, K.J., and Jones, R.J., 2012, Correlation of early Paleogene global diversity patterns of large benthic foraminifera with Paleocene-Eocene hyperthermal events: Palaios, v. 27, no. 4, p. 235-251, https://doi.org/10.2110/palo.2010.p10-109r.","productDescription":"17 p.","startPage":"235","endPage":"251","ipdsId":"IP-022808","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":355484,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":355480,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.geoscienceworld.org/sepm/palaios/article/27/4/235/146258/correlation-of-early-paleogene-global-diversity"}],"volume":"27","issue":"4","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2012-04-03","publicationStatus":"PW","scienceBaseUri":"5b46f6ebe4b060350a15d3bc","contributors":{"authors":[{"text":"Whidden, Katherine J. 0000-0002-7841-2553 kwhidden@usgs.gov","orcid":"https://orcid.org/0000-0002-7841-2553","contributorId":3960,"corporation":false,"usgs":true,"family":"Whidden","given":"Katherine","email":"kwhidden@usgs.gov","middleInitial":"J.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"preferred":true,"id":739484,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, Robert J.","contributorId":206118,"corporation":false,"usgs":false,"family":"Jones","given":"Robert","email":"","middleInitial":"J.","affiliations":[{"id":37250,"text":"Natural History Museum, London","active":true,"usgs":false}],"preferred":false,"id":739485,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

As part of a large-scale ambient groundwater study, we evaluated chemical mixtures across multiple chemical classes, and included more chemical contaminants than in previous studies of mixtures in public-supply wells. We (1) assessed the occurrence of chemical mixtures in untreated source-water samples from public-supply wells, (2) determined the composition of the most frequently occurring mixtures, and (3) characterized the potential toxicity of mixtures using a new screening approach. The U.S. Geological Survey collected one untreated water sample from each of 383 public wells distributed across 35 states, and analyzed the samples for as many as 91 chemical contaminants. Concentrations of mixture components were compared to individual human-health benchmarks; the potential toxicity of mixtures was characterized by addition of benchmark-normalized component concentrations. Most samples (84%) contained mixtures of two or more contaminants, each at concentrations greater than one-tenth of individual benchmarks. The chemical mixtures that most frequently occurred and had the greatest potential toxicity primarily were composed of trace elements (including arsenic, strontium, or uranium), radon, or nitrate. Herbicides, disinfection by-products, and solvents were the most common organic contaminants in mixtures. The sum of benchmark-normalized concentrations was greater than 1 for 58% of samples, suggesting that there could be potential for mixtures toxicity in more than half of the public-well samples. Our findings can be used to help set priorities for groundwater monitoring and suggest future research directions for drinking-water treatment studies and for toxicity assessments of chemical mixtures in water resources.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2012.05.044","usgsCitation":"Toccalino, P.L., Norman, J.E., and Scott, J.C., 2012, Chemical mixtures in untreated water from public-supply wells in the U.S. — Occurrence, composition, and potential toxicity: Science of the Total Environment, v. 431, p. 262-270, https://doi.org/10.1016/j.scitotenv.2012.05.044.","productDescription":"9 p.","startPage":"262","endPage":"270","ipdsId":"IP-030178","costCenters":[],"links":[{"id":355349,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"431","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b46f6ece4b060350a15d3be","contributors":{"authors":[{"text":"Toccalino, Patricia L. 0000-0003-1066-1702 ptocca@usgs.gov","orcid":"https://orcid.org/0000-0003-1066-1702","contributorId":933,"corporation":false,"usgs":true,"family":"Toccalino","given":"Patricia","email":"ptocca@usgs.gov","middleInitial":"L.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":false,"id":739023,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Norman, Julia E. 0000-0002-2820-6225 jnorman@usgs.gov","orcid":"https://orcid.org/0000-0002-2820-6225","contributorId":3832,"corporation":false,"usgs":true,"family":"Norman","given":"Julia","email":"jnorman@usgs.gov","middleInitial":"E.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":739024,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Scott, Jonathon C. jcscott@usgs.gov","contributorId":5449,"corporation":false,"usgs":true,"family":"Scott","given":"Jonathon","email":"jcscott@usgs.gov","middleInitial":"C.","affiliations":[],"preferred":true,"id":739025,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

PBDE concentrations in prey fish caught in the Saginaw River, the primary tributary to Saginaw Bay, and in Saginaw Bay during 2005 and 2007 also were determined. Mature male and mature female walleyes averaged 70.3 ng/g and 24.8 ng/g, respectively, in ΣPBDE, which was equal to the sum of concentrations of six PBDE congeners (BDE-28, BDE-47, BDE-99, BDE-100, BDE-153, and BDE-154). This sex difference was likely due to males spending more time in the Saginaw River system than females. Prey fish captured in the Saginaw River were roughly ten times higher in ΣPBDE than those caught in Saginaw Bay. BDE-47 was the predominant congener in both walleyes and prey fish, and this congener contributed about 50%, on average, to ΣPBDE. Congener profiles differed significantly between the two sexes of walleyes. In contrast, congener profiles of the prey fish did not differ significantly between the river-caught fish and the bay-caught fish. One plausible explanation for these congener profile results was that net trophic transfer efficiencies of PBDEs to walleyes from their prey were similar for all congeners except BDE-28, and that diet composition differed between the two sexes of walleyes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jglr.2011.11.007","usgsCitation":"Madenjian, C.P., Trombka, A.W., Rediske, R.R., Jude, D.J., and O'Keefe, J., 2012, Sex difference in polybrominated diphenyl ether concentrations of walleyes: Journal of Great Lakes Research, v. 38, no. 1, p. 167-175, https://doi.org/10.1016/j.jglr.2011.11.007.","productDescription":"9 p.","startPage":"167","endPage":"175","ipdsId":"IP-031071","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":265002,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265001,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2011.11.007"}],"country":"United States","state":"Michigan","otherGeospatial":"Saginaw Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -83.9255,43.6159 ], [ -83.9255,44.0381 ], [ -83.4215,44.0381 ], [ -83.4215,43.6159 ], [ -83.9255,43.6159 ] ] ] } } ] }","volume":"38","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4c225e4b0e8fec6ce05d5","contributors":{"authors":[{"text":"Madenjian, Charles P. 0000-0002-0326-164X cmadenjian@usgs.gov","orcid":"https://orcid.org/0000-0002-0326-164X","contributorId":2200,"corporation":false,"usgs":true,"family":"Madenjian","given":"Charles","email":"cmadenjian@usgs.gov","middleInitial":"P.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":470611,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trombka, Autumn W.","contributorId":36432,"corporation":false,"usgs":true,"family":"Trombka","given":"Autumn","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":470613,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rediske, Richard R.","contributorId":79053,"corporation":false,"usgs":true,"family":"Rediske","given":"Richard","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":470614,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jude, David J.","contributorId":11986,"corporation":false,"usgs":true,"family":"Jude","given":"David","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":470612,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"O'Keefe, James P.","contributorId":99499,"corporation":false,"usgs":true,"family":"O'Keefe","given":"James P.","affiliations":[],"preferred":false,"id":470615,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Recent studies in the Alaska Range north of the Denali fault add significantly to the recognition of Quaternary deformation in this active orogen. Faults and folds active during the Quaternary occur over a length of ∼500 km along the northern flank of the Alaska Range, extending from Mount McKinley (Denali) eastward to the Tok River valley. These faults exist as a continuous system of active structures, but we divide the system into four regions based on east-west changes in structural style. At the western end, the Kantishna Hills have only two known faults but the highest rate of shallow crustal seismicity. The western northern foothills fold-thrust belt consists of a 50-km-wide zone of subparallel thrust and reverse faults. This broad zone of deformation narrows to the east in a transition zone where the range-bounding fault of the western northern foothills fold-thrust belt terminates and displacement occurs on thrust and/or reverse faults closer to the Denali fault. The eastern northern foothills fold-thrust belt is characterized by ∼40-km-long thrust fault segments separated across left-steps by NNE-trending left-lateral faults. Altogether, these faults accommodate much of the topographic growth of the northern flank of the Alaska Range.</p><p id=\"p-2\">Recognition of this thrust fault system represents a significant concern in addition to the Denali fault for infrastructure adjacent to and transecting the Alaska Range.

Deposits of the Idaho cobalt belt comprise three types: (1) strata-bound sulfide lenses in the Blackbird district, which are cobaltite and, less commonly, chalcopyrite rich with locally abundant gold, native bismuth, bismuthinite, xenotime, allanite, monazite, and the Be-rich silicate gadolinite-(Y), with sparse uraninite, stannite, and Bi tellurides, in a gangue of quartz, chlorite, biotite, muscovite, garnet, tourmaline, chloritoid, and/or siderite, with locally abundant fluorapatite or magnetite; (2) discordant tourmalinized breccias in the Blackbird district that in places have concentrations of cobaltite, chalcopyrite, gold, and xenotime; and (3) strata-bound magnetite-rich lenses in the Iron Creek area, which contain cobaltiferous pyrite and locally sparse chalcopyrite or xenotime. Most sulfide-rich deposits in the Blackbird district are enclosed by strata-bound lenses composed mainly of Cl-rich Fe biotite; some deposits have quartz-rich envelopes.</p><p id=\"p-2\">Whole-rock analyses of 48 Co- and/or Cu-rich samples show high concentrations of Au (up to 26.8 ppm), Bi (up to 9.16 wt %), Y (up to 0.83 wt %), ∑REEs (up to 2.56 wt %), Ni (up to 6,780 ppm), and Be (up to 1,180 ppm), with locally elevated U (up to 124 ppm) and Sn (up to 133 ppm); Zn and Pb contents are uniformly low (≤821 and ≤61 ppm, respectively). Varimax factor analysis of bulk compositions of these samples reveals geochemically distinct element groupings that reflect statistical associations of monazite, allanite, and xenotime; biotite and gold; detrital minerals; chalcopyrite and sparse stannite; quartz; and cobaltite with sparse selenides and tellurides. Significantly, Cu is statistically separate from Co and As, consistent with the general lack of abundant chalcopyrite in cobaltite-rich samples.</p><p id=\"p-3\">Paragenetic relations determined by scanning electron microscopy indicate that the earliest Y-REE-Be mineralization preceded deposition of Co, Cu, Au, and Bi. Allanite, xenotime, and gadolinite-(Y) commonly occur as intergrowths with and inclusions in cobaltite; the opposite texture is rare. Monazite, in contrast, forms a poikiloblastic matrix to cobaltite and thin rims on allanite and xenotime, reflecting a later metamorphic paragenesis. Allanite and xenotime also show evidence of late dissolution and reprecipitation, forming discordant rims on older anhedral allanite and xenotime and separate euhedral crystals of each mineral. Textural data suggest extensive deformation of the deposits by folding and shearing, and by pervasive recrystallization, all during Cretaceous metamorphism.

These ages are used together with mineralogical and geochemical data from the present study to support an epigenetic, IOCG model for Fe-Co-Cu-Au-Bi-Y-REE deposits of the Idaho cobalt belt. A sulfide facies variant of IOCG deposits is proposed for the Blackbird district, in which reducing hydrothermal conditions favored deposition of sulfide minerals over iron oxides. This new model includes Mesoproterozoic vein mineralization and related Fe-Cl metasomatism that formed the biotite-rich lenses, a predominantly felsic magmatic source for metals in the deposits, given their local abundance of Y, REEs, and Be, and a major sedimentary component in the hydrothermal fluids based on independent sulfur isotope and boron isotope data for sulfides and ore-related tourmaline, respectively.</p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/econgeo.107.6.1089","usgsCitation":"Slack, J.F., 2012, Strata-bound Fe-Co-Cu-Au-Bi-Y-REE deposits of the Idaho Cobalt Belt: Multistage hydrothermal mineralization in a magmatic-related iron oxide copper-gold system: Economic Geology, v. 107, no. 6, p. 1089-1113, https://doi.org/10.2113/econgeo.107.6.1089.","productDescription":"25 p.","startPage":"1089","endPage":"1113","ipdsId":"IP-030528","costCenters":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":346338,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"107","issue":"6","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2012-09-20","publicationStatus":"PW","scienceBaseUri":"59d3502ce4b05fe04cc34d84","contributors":{"authors":[{"text":"Slack, John F. 0000-0001-6600-3130 jfslack@usgs.gov","orcid":"https://orcid.org/0000-0001-6600-3130","contributorId":1032,"corporation":false,"usgs":true,"family":"Slack","given":"John","email":"jfslack@usgs.gov","middleInitial":"F.","affiliations":[{"id":387,"text":"Mineral Resources Program","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":711688,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Some of the first hypotheses proposed to explain global patterns of amphibian declines included the effects of non-native species (Barinaga 1990; Blaustein and Wake 1990; Wake and Morowitz 1991). Evidence for the impact of non-native species on amphibians stems (1) from correlative research that relates the distribution or abundance of a species to that of a putative non-native species, and (2) from experimental tests of the effects of a non-native species on survival, growth, development or behaviour of a target species (Kats and Ferrer 2003). Over the past two decades, research on the effects of non-native species on amphibians has mostly focused on introduced aquatic predators, particularly fish. Recent research has shifted to more complex ecological relationships such as influences of sub-lethal stressors (e.g. contaminants) on the effects of non-native species (Linder et al. 2003; Sih et al. 2004), non-native species as vectors of disease (Daszak et al. 2004; Garner et al. 2006), hybridization between non-natives and native congeners (Riley et al. 2003; Storfer et al. 2004), and the alteration of food-webs by non-native species (Nystrom et al. 2001). Other research has examined the interaction of non-native species in terms of facilitation (i.e. one non-native enabling another to become established or spread) or the synergistic effects of multiple non-native species on native amphibians, the so-called invasional meltdown hypothesis (Simerloff and Von Holle 1999). Although there is evidence that some non-native species may interact (Ricciardi 2001), there has yet to be convincing evidence that such interactions have led to an accelerated increase in the number of non-native species and cumulative impacts are still uncertain (Simberloff 2006). Applied research on the control, eradication, and management of non-native species has only just begun but some promising results have already emerged (see below), giving hope to a very difficult conservation issue. This chapter provides an overview of the role of non-native species in amphibian declines and summarizes the current state of knowledge of non-native species that are known, or considered to be, a threat to amphibian species and populations. The biological and socio-economic issues of non-native species control are examined and brief case studies of successful eradication programmes are provided.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Conservation and decline of amphibians: ecological aspects, effect of humans, and management","language":"English","publisher":"Surrey Beatty","publisherLocation":"Baulkham Hills, New South Wales, Australia","usgsCitation":"Wilkinson, J.W., 2012, Ecological impacts of non-native species, chap. <i>of</i> Conservation and decline of amphibians: ecological aspects, effect of humans, and management, p. 3343-3382.","productDescription":"39 p.","startPage":"3343","endPage":"3382","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":307464,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f565e4b0bc0bec0a1620","contributors":{"authors":[{"text":"Wilkinson, John W.","contributorId":147014,"corporation":false,"usgs":false,"family":"Wilkinson","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":569878,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The Glen Canyon Dam Adaptive Management Program (&lsquo;the Program&rsquo;) was formally established in 1997 to fulfill a statutory requirement in the 1992 Grand Canyon Protection Act (GCPA). The GCPA aimed to improve natural resource conditions in the Colorado River corridor in the Glen Canyon National Recreation Area and Grand Canyon National Park, Arizona that were affected by the Glen Canyon dam. The Program achieves this by using science and a variety of stakeholder perspectives to inform decisions about dam operations. Since the Program started the ecosystem is now much better understood and several biological and physical improvements have been achieved. These improvements include: (i) an estimated 50% increase in the adult population of endangered humpback chub (Gila cypha) between 2001 and 2008, following previous decline; (ii) a 90% decrease in non-native rainbow trout (Oncorhynchus mykiss), which are known to compete with and prey on native fish, as a result of removal experiments; and (iii) the widespread reappearance of sandbars in response to an experimental high-flow release of dam water in March 2008.Although substantial progress has been made, the Program faces several immediate challenges. These include: (i) defining specific, measurable objectives and desired future conditions for important natural, cultural and recreational attributes to inform science and management decisions; (ii) implementing structural and operational changes to improve collaboration among stakeholders; (iii) establishing a long-term experimental programme and management plan; and (iv) securing long-term funding for monitoring programmes to assess ecosystem and other responses to management actions. Addressing these challenges and building on recent progress will require strong and consistent leadership from the US Department of the Interior officials who guide the Program.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"River conservation and management","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"John Wiley & Sons, Ltd","publisherLocation":"Chester, UK","doi":"10.1002/9781119961819.ch26","usgsCitation":"Hamill, J.F., and Melis, T., 2012, The Glen Canyon Dam adaptive management program: Progress and immediate challenges, chap. <i>of</i> River conservation and management, p. 325-338, https://doi.org/10.1002/9781119961819.ch26.","productDescription":"19 p.","startPage":"325","endPage":"338","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-023715","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":308085,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Glen Canyon Dam","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.49449348449707,\n              36.924988609754976\n            ],\n            [\n              -111.47174835205078,\n              36.924988609754976\n            ],\n            [\n              -111.47174835205078,\n              36.94268922503273\n            ],\n            [\n              -111.49449348449707,\n              36.94268922503273\n            ],\n            [\n              -111.49449348449707,\n              36.924988609754976\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationDate":"2012-02-17","publicationStatus":"PW","scienceBaseUri":"560bb707e4b058f706e53eec","contributors":{"editors":[{"text":"Boon, Philip J.","contributorId":147624,"corporation":false,"usgs":false,"family":"Boon","given":"Philip","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":572179,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Raven, Paul J.","contributorId":147625,"corporation":false,"usgs":false,"family":"Raven","given":"Paul","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":572180,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Hamill, John F.","contributorId":43061,"corporation":false,"usgs":true,"family":"Hamill","given":"John","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":572177,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Melis, Theodore S. 0000-0003-0473-3968 tmelis@usgs.gov","orcid":"https://orcid.org/0000-0003-0473-3968","contributorId":1829,"corporation":false,"usgs":true,"family":"Melis","given":"Theodore S.","email":"tmelis@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":572178,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Many ESS, including melanterite, rozenite, siderotil, copiapite, halotrichite, coquimbite, epsomite, potash alum, and gypsum, are known to occur in Indiana. Because they build up on the gob-pile surface during dry periods and release acidity and metals in storm flushes, it is essential to understand the mineralogical and geochemical parameters that control ESS formation and dissolution in mine settings. The Friar Tuck site, in southwestern Indiana, is an ideal location for demonstrating the role of ESS in the generation of acid mine drainage and is included as a case study in this report. Examination of two gob piles at the site (northwest and southeast), in the same setting but with different mineralogies and depositional and reclamation histories, provides a unique opportunity to consider the transferability of lessons learned about the ESS between different sites.</p>\n<p>Hydraulic and chemical data, including data on aqueous and solid states (coal refuse and ESS), were collected from streams (adjacent to the gob piles and further downstream), seeps, surface runoff, and saturated and unsaturated groundwater at the northwest and southeast gob piles during 1988&ndash;89 and 1990&ndash;92, respectively. Samples were analyzed in the field for bulk indicators and in a laboratory (Indiana Geological Survey, Geochemistry Section) for concentrations of major and trace elements.</p>\n<p>Values of pH and specific conductance at the southeast gob pile indicated a trend of declining water quality with duration of the dry season, followed by dilution and improved water quality during the wet season; similar observations were made at the northwest gob pile. Concentrations of key water-quality indicators for the northwest and southeast gob piles show that acidity and concentrations of sulfate and iron are notably lower in the surface runoff and groundwater in saturated and unsaturated refuse at the southeast gob pile compared to the northwest gob pile. The dissolution of ESS is likely the cause for the decrease in water quality at both gob piles, but it has a greater effect at the northwest gob pile.</p>\n<p>The results of this study indicate that some generalizations about the effect of ESS on water quality (for example, the conditions that favor the precipitation of specific ESS; the development of acidic, metal-rich drainage; and so on) can be transferred from one coal-waste site to another. However, the specific geochemistry of the gob pile, the age and history of refuse, the source rock, and the coal-processing and reclamation activities at the specific site will determine the extent to which the processes described in this and other papers can be applied to unstudied gob piles.</p>\n<p>&nbsp;</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Effects of abandoned mine

The package contains a graphical preprocessor for constructing simulations, a postprocessor for displaying simulation results, and numerical models that solve for flow and solute transport (VS2DT) and flow and heat transport (VS2DH). Flow is described by the Richards equation, and solute and heat transport are described by advection-dispersion equations; the finite-difference method is used to solve these equations. Problems can be simulated in one, two, or three (assuming radial symmetry) dimensions. This article provides an overview of calibration techniques that have been used with VS2DI; included is a detailed description of calibration procedures used in simulating the interaction between groundwater and a stream fed by drainage from agricultural fields in central Indiana. Brief descriptions of VS2DI and the various types of problems that have been addressed with the software package are also presented.</span></p>","language":"English","publisher":"ASABE","doi":"10.13031/2013.42238","usgsCitation":"Healy, R.W., and Essaid, H.I., 2012, VS2DI: Model use, calibration, and validation: Transactions of the ASABE, v. 55, no. 4, p. 1249-1260, https://doi.org/10.13031/2013.42238.","productDescription":"12 p.","startPage":"1249","endPage":"1260","ipdsId":"IP-034395","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":343374,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"55","issue":"4","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"595dfab9e4b0d1f9f056a7b9","contributors":{"authors":[{"text":"Healy, Richard W. 0000-0002-0224-1858 rwhealy@usgs.gov","orcid":"https://orcid.org/0000-0002-0224-1858","contributorId":658,"corporation":false,"usgs":true,"family":"Healy","given":"Richard","email":"rwhealy@usgs.gov","middleInitial":"W.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":703466,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Essaid, Hedeff I. 0000-0003-0154-8628 hiessaid@usgs.gov","orcid":"https://orcid.org/0000-0003-0154-8628","contributorId":2284,"corporation":false,"usgs":true,"family":"Essaid","given":"Hedeff","email":"hiessaid@usgs.gov","middleInitial":"I.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":703465,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
