The subdued, vegetated moraines of the older group have been found at 25 sites, mainly in the central part of the Lewis Range. These older moraines are in places overlain by the Mazama ash. Although the exact age of the moraines has not been determined by radiocarbon dating, vegetative evidence and correlation with other pre-altithermal age moraines in the Rocky Mountains suggest that these older moraines date from 10 000 BP or earlier. Whether these moraines are the product of a separate advance after the end of the Wisconsin glaciation or are simply the product of the last advance or stillstand of Wisconsin glaciers before final deglaciation is not known.Moraines of the younger group, consisting of fresh bouldery rubble, are common throughout Glacier Park. Tree-ring analyses indicate that some of these younger moraines were deposited by advances that culminated during the mid-19th century. At that time there were more than 150 glaciers in Glacier Park. This episode of mid-19th century climatic cooling resulted in the most extensive glacial advance in this region since the end of the Wisconsin glaciation.Present-day glaciers have shrunk drastically from their mid-19th century positions; more than half the glaciers present during that time no longer exist. Much of this retreat occurred between 1920 and the mid-1940's, corresponding to a period of above-average summer temperatures and below-average annual precipitation in this region. Between 1966 and 1979, several of the larger glaciers in the Mount Jackson area of Glacier Park advanced as much as 100 m.</span></p>","language":"English","publisher":"Canadian Science

The geothermal ground-water system underlying the main aquifer system was examined by calculating thermodynamic mineral saturation indices, stable-isotope ratios of geothermal water, geothermometry, and radiocarbon dating.</p><p>Water budgets, hydrologic arguments, and isotopic analyses for the eastern Snake River Plain aquifer system demonstrate that most, if not all, water is of local meteoric and not juvenile or formation origin. Solute-balance, isotopic, mineralogic, and thermodynamic arguments suggest that about 20 percent of the solutes are derived from reactions with rocks forming the aquifer framework.</p><p>Solute reactions indicate that calcite and silica are precipitated in the aquifer. Mineralogic evidence and thermodynamic arguments suggest that olivine, pyroxene, pyrite, and anhydrite are being dissolved and plagioclase is being weathered. Large amounts of sodium and chloride, relative to their concentration in the igneous rock, are being removed from the aquifer. Release of fluids from inclusions in the igneous rocks, and initial flushing of grain boundaries and pores of detrital marine sediments in interbeds are believed to be the source of the sodium chloride. Identification and quantification of reactions controlling solute concentrations in ground water in the eastern plain indicate that the aquifer is not a large mixing vessel that simply stores and transmits water and solutes but is undergoing diagenesis and is both a source and sink for solutes.</p><p>Evaluation of solute concentrations and stable-isotope ratios of hydrogen, oxygen, carbon, and sulfur along ground-water flowpaths that transect irrigated areas suggests that irrigation water may have altered solute concentrations and isotope ratios in the eastern Snake River Plain aquifer system. The changes, however, have been small, owing to similarity of solute concentrations in applied irrigation water and in native ground water and rapid movement and large dispersivity of the aquifer.</p><p>Reactions controlling solutes in the western Snake River basin are believed to be similar to those in the eastern basin but, because of different hydrologic conditions, a definitive analysis could not be made.</p><p>The regional geothermal system that underlies the Snake River Plain contains total dissolved solids similar to those in the overlying Snake River Plain aquifer system but contains higher concentrations of sodium, bicarbonate, silica, fluoride, sulfate, chloride, arsenic, boron, and lithium, and lower concentrations of calcium, magnesium, and hydrogen. These solutes are believed to be derived from reactions similar to those in the Snake River Plain aquifer system, except that ion exchange may be a significant mechanism controlling solute concentrations in the geothermal system.</p><p>Geothermometry calculations of selected ground-water samples from known geothermal areas throughout the basin suggest that the geothermal system is large in areal extent but has relatively low temperatures. Approximately half of the silica-quartz calculated water temperatures are greater than 90 degrees Celsius. Radiocarbon dating of geothermal water in the Salmon Falls and Bruneau-Grand View areas in the south-central part of the Snake River basin suggests that residence time of the geothermal water is about 17,700 years.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr86247","collaboration":"A contribution of the Regional Aquifer-System Analysis program","usgsCitation":"Wood, W.W., and Low, W.H., 1987, Solute geochemistry of the Snake River plain regional aquifer system, Idaho and eastern Oregon: U.S. Geological Survey Open-File Report 86-247, xi, 146 p., https://doi.org/10.3133/ofr86247.","productDescription":"xi, 146 p.","costCenters":[],"links":[{"id":154007,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1986/0247/report-thumb.jpg"},{"id":382936,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1986/0247/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho, Oregon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.04833984375001,\n              42.06560675405716\n            ],\n            [\n              -111.15966796875,\n              42.06560675405716\n            ],\n            [\n              -111.15966796875,\n              48.951366470947725\n            ],\n            [\n              -117.04833984375001,\n              48.951366470947725\n            ],\n            [\n              -117.04833984375001,\n              42.06560675405716\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e479de4b07f02db491f0a","contributors":{"authors":[{"text":"Wood, Warren W.","contributorId":213538,"corporation":false,"usgs":false,"family":"Wood","given":"Warren","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":184469,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Low, Walton H.","contributorId":92672,"corporation":false,"usgs":true,"family":"Low","given":"Walton","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":184470,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The upper 150 ft of sedimentary deposits in the inner valley, mostly alluvium that consists of cobbles, gravel, sand, silt, and clay, was emphasized because of its susceptibility to contamination. A map of the water table on February 28, 1986 shows that flow generally is parallel to the river and the gradient is approximately 5 ft/mi or 0.0001. In areas affected by municipal and industrial groundwater withdrawals, declines may exceed 10 ft, and the water table gradient is as much as 20 ft/mi or 0.004. The gradient also is steeper near drains, particularly during the irrigation season. In the area east of the community of Mountainview the direction of water movement may have reversed between 1936 and 1986; flow near appears to be toward the east or southeast. Groups of four piezometers, each screened at a different depth, were monitored to describe seasonal changes of the water table. Vertical gradients between piezometers ranged from 0.014 upward to 0.047 downward from July 1985 to June 1986, but were downward most of the year, particulary during the irrigation season. The horizontal hydraulic conductivity of a 15-ft-thick clay and silt bed beneath Rio Bravo Boulevard is estimated to be 0.0001 ft/day. The average interstitial velocity down through this bed is estimated to range from about 0.0002 to 0.0005 ft/day. The fluctuations of the water table at the piezometers nearest the Rio Grande do not appear to be affected by the riverside drain.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri874015","usgsCitation":"Peter, K.D., 1987, Ground-water flow and shallow-aquifer properties in the Rio Grande inner valley south of Albuquerque, Bernalillo County, New Mexico: U.S. Geological Survey Water-Resources Investigations Report 87-4015, iv, 29 p., https://doi.org/10.3133/wri874015.","productDescription":"iv, 29 p.","costCenters":[],"links":[{"id":57994,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1987/4015/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123690,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1987/4015/report-thumb.jpg"},{"id":415599,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46703.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"New Mexico","county":"Bernalillo County","city":"Albuquerque","otherGeospatial":"Rio Grande Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -106.5833,\n              35.095\n            ],\n            [\n              -106.7292,\n              35.095\n            ],\n            [\n              -106.7292,\n              34.9394\n            ],\n            [\n              -106.5833,\n              34.9394\n            ],\n            [\n              -106.5833,\n              35.095\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cd65","contributors":{"authors":[{"text":"Peter, K.

In this method, the natural stable isotopic composition of the pyritic and organic sulphur in coal is used as a tracer to follow their mobility during the desulphurization process. This tracer method is based on the fact that the isotopic compositions of pyritic and organic sulphur are significantly different in some coals. Isotopic results of pyrolysis experiments at temperatures ranging from 350 to 750 °C indicate that the sulphur released with the volatiles is predominantly organic sulphur. The pyritic sulphur is evolved in significant quantities only when pyrolysis temperatures exceed 500 °C. The presence of pyrite seems to have no effect on the amount of organic sulphur evolved during pyrolysis. The chemical and isotopic mass balances achieved from three different samples of the Herrin (No. 6) coal of the Illinois Basin demonstrate that this stable isotope tracer method is quantitative. The main disadvantage of this tracing technique is that not all coals contain isotopically distinct organic and pyritic sulphur.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-2361(87)90279-1","issn":"00162361","usgsCitation":"Liu, C., Hackley, K.C., and Coleman, D., 1987, Use of stable

The ??15O values for these minerals decrease with increasing temperatures. The values indicate that these hydrothermal minerals precipitated in isotopic equilibrium with water currently present in the reservoirs. The ??18O values of quartz and calcite from the andesite and basalt flows (700-932 m) have isotopic values which require that the equilibrated water ??18O values increase slightly (- 11.3 to -9.2???) with increasing measured temperatures (150-265??C). The lithic tuffs and brecciated lava flows (300-700 m) contain widespread siderite. Calculated oxygen isotopic compositions of waters in equilibrium with siderite generally increase with increasing temperatures (76-100??C). The ??18O values of siderite probably result from precipitation in water produced by mixing various amounts of the deep hydrothermal water (- 10.5 ???) with meteoric water (- 15.5 ???) recharged within the caldera. The ??13C values of calcite and siderite decrease with increasing temperatures and show that these minerals precipitated in isotopic equilibrium with CO2 of about -8 ???. The ??18O values of weakly altered (<5% alteration of plagioclase) whole-rock samples decrease with increasing temperatures above 100??C, indicating that exchange between water and rock is kinetically controlled. The water/rock mass ratios decrease with decreasing temperatures. The ??18O values of rocks from the bottom of Newberry 2 show about 40% isotopic exchange with the reservoir water. The calculated ??18O and ??D values of bottom hole water determined from the fluid produced during the 20 hour flow test are -10.2 and -109???, respectively. The ??D value of the hydrothermal water indicates recharge from outside the caldera. ?? 1987.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Carothers, W., Mariner, R.H., and Keith, T.E., 1987, Isotope geochemistry of minerals and fluids from Newberry volcano, Oregon: Journal of Volcanology and Geothermal Research, v. 31, no. 1-2, p. 47-63.","startPage":"47","endPage":"63","numberOfPages":"17","costCenters":[],"links":[{"id":223711,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3f89e4b0c8380cd645e1","contributors":{"authors":[{"text":"Carothers, W.W.","contributorId":43803,"corporation":false,"usgs":true,"family":"Carothers","given":"W.W.","email":"","affiliations":[],"preferred":false,"id":370624,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mariner, Robert H.","contributorId":81075,"corporation":false,"usgs":true,"family":"Mariner","given":"Robert","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":370625,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keith, T.

Analysis procedures include ray theory calculations and synthetic seismograms computed using reflectivity techniques. The P wave velocity structure beneath the Canadian Shield is virtually identical to that beneath the Baltic Shield to a depth of at least 800 km. Two major layers with a total thickness of about 42 km characterize the crust of these shield regions. Features of the upper mantle of these region include velocity discontinuities at depths of about 74 km, 330 km, 430 km and 700 km. A 13 km thick P wave low velocity channel beginning at a depth of about 94 km is also present. A number of problems associated with record section interpretation are identified and a generalized approach to seismic profile analysis using many record sections is described. The S wave velocity structure beneath the Canadian Shield is derived from constrained surface wave data. The thickness of the lithosphere beneath the Canadian and Baltic Shields is determined to be 95-100 km. The continental plate thickness may be the same as the lithospheric thickness, although available data do not exclude the possibility of the continental plate being thicker than the lithosphere. ?? 1987 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00874495","issn":"00334553","usgsCitation":"Masse, R., 1987, Crustal and upper mantle structure of stable continental regions in North America and northern Europe: Pure and Applied Geophysics PAGEOPH, v. 125, no. 2-3, p. 205-239, https://doi.org/10.1007/BF00874495.","startPage":"205","endPage":"239","numberOfPages":"35","costCenters":[],"links":[{"id":224247,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205460,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00874495"}],"volume":"125","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fcd8e4b0c8380cd4e46f","contributors":{"authors":[{"text":"Masse, R.P.","contributorId":87182,"corporation":false,"usgs":true,"family":"Masse","given":"R.P.","email":"","affiliations":[],"preferred":false,"id":370575,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

For the purposes of sampling building materials, census and land use variables were used to identify similar strata. In the Metropolitan Statistical Area of a cityscape, the census tract is the smallest unit for which census data are summarized and digitized boundaries are available. For purposes of this analysis, census data on total population, total number of housing units, and number of singleunit dwellings were aggregated into variables of persons per square kilometer and proportion of housing units in single-unit dwellings. The level 2 categories of the U.S. Geological Survey's land use and land cover data base were aggregated into variables of proportion of residential land with buildings, proportion of nonresidential land with buildings, and proportion of open land. The cityscape was stratified, from these variables, into environmental strata of Urban Central Business District, Urban Livelihood Industrial Commercial, Urban Multi-Family Residential, Urban Single Family Residential, Non-Urban Suburbanizing, and Non-Urban Rural. The New England region was chosen as a region with commonality of building materials, and a procedure developed for trial classification of census tracts into one of the strata. Final stratification was performed by discriminant analysis using the trial classification and prior probabilities as weights.

The single divergence from the Bolivian association is tungsten, which is totally lacking in the U. S. Virgin Islands. The delineated geochemical patterns transect all exposed rock types on the islands, including the Kingshill Marl of late Miocene age, on St. Croix. Some relationship between the geochemical patterns and the major mapped faults can be seen - especially on St. Croix. K-Ar age dating of rocks from St. Thomas and St. John indicates that they are of Tertiary rather than Cretaceous age. This and the apparent contemporaneity of the mineralization with the St. Croix graben infilling indicate a very late Miocene age for the mineralization.","largerWorkTitle":"Preprint - Society of Mining Engineers of AIME","conferenceTitle":"Soc of Mining Engineers, Preprints for Presentation at the SME Annual Meeting.","conferenceLocation":"Denver, CO, USA","language":"English","publisher":"Soc of Mining Engineers of AIME","publisherLocation":"Littleton, CO, USA","usgsCitation":"Alminas, H.V., and Tucker, R.E., 1987, LEAD, TIN, AND PRECIOUS-METAL MINERALIZATION IN THE U.

The casts, which are as much as 11 cm in diameter and as much as 1.6 m long, were formed by passive silicilastic and carbonate sedimentation into apparently abandoned lungfish burrows. Locally, the burrow fillings are overwhelmingly abundant, and many intersect and have destroyed former burrow fillings. Superposition of bioturbation episodes has obliterated most primary sedimentary structures. This bioturbation has contributed to the mottled coloration and the knobby-weathering texture of the rocks. The burrow-fillings occur ubiquitously in three lithofacies, comprising 1) purple- and white-mottled, silicified sandstone and siltstone, 2) red and brown siltstone and mudstone, and 3) pink and green limestone. These strata were deposited in a continental environment that included fluvial channels and floodplains, sand sheets and playa mudflats, and lacustrine basins, marshes, and deltas. The identification of the trace fossils as the positive casts of lungfish burrows is based on their morphologic similarity to previously identified lungfish burrows and to available hand specimens. The widespread occurrence of the lungfish burrows in the Chinle and Dolores Formations attests to the extensive habitat that supported lungfish in the Late Triassic and to conditions favorable for burrow preservation. Analogy with the environments that support modern lungfish populations suggests that the Late Triassic climate in the study area provided sufficient moisture to support large populations of lungfish and that this climate was probably punctuated by seasonally dry periods.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F8B7A-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Dubiel, R.F., Blodgett, R., and Bown, T.M., 1987, Lungfish burrows in the Upper Triassic Chinle and Dolores Formations, Colorado Plateau: Journal of Sedimentary Petrology, v. 57, no. 3, p. 512-521, https://doi.org/10.1306/212F8B7A-2B24-11D7-8648000102C1865D.","productDescription":"10 p.","startPage":"512","endPage":"521","numberOfPages":"10","costCenters":[],"links":[{"id":224085,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"57","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4a9ee4b0c8380cd68ee5","contributors":{"authors":[{"text":"Dubiel, R.

We suggest that the Archean crustal component reflects an African connection, in which old Archean crust was underplated to the Avalon zone microplate in the late Paleozoic during collision of Gondwanaland with Avalonia.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0012-821X(87)90204-4","issn":"0012821X","usgsCitation":"Zartman, R., and Don, H.O., 1987, Archean inheritance in zircon from late Paleozoic granites from the Avalon zone of southeastern New England: An African connection: Earth and Planetary Science Letters, v. 82, no. 3-4, p. 305-315, https://doi.org/10.1016/0012-821X(87)90204-4.","productDescription":"11 p.","startPage":"305","endPage":"315","numberOfPages":"11","costCenters":[],"links":[{"id":224028,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"82","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ed30e4b0c8380cd496a0","contributors":{"authors":[{"text":"Zartman, R.

For these sediments, exchangeable ammonium, and thereby adsorbed ammonium concentrations, were determined directly using an ammonia electrode in alkaline sediment suspensions. Ammonia electrode data were comparable to data obtained by KCl extraction of fresh sediment. The conventional unitless ammonium adsorption coefficient, calculated as the slope of the regression line drawn when sediment-adsorbed ammonium (μmol g</span><sup>−1</sup><span>&nbsp;dry wt of sediment) is plotted against interstitial water ammonium (μmol g</span><sup>−1</sup><span>&nbsp;dry wt sediment), is 1·5 for this system. When a modified ammonium adsorption coefficient is calculated from sediment-adsorbed ammonium concentrations and a ratio of interstitial water ammonium and potassium concentrations, the regression equation through the data has a zero intercept and is more nearly linear than the regression equation of data based on conventional calculations. The use of a ratio including ammonium and potassium concentrations in the interstitial water term takes into account ionic strength variations in the estuary and competition between ammonium and potassium for adsorption sites.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0272-7714(87)90022-9","issn":"02727714","usgsCitation":"Simon, N., and Kennedy, M., 1987, The
