These age correlations and the distribution of fossils, plus the biofacies of conodonts and brachiopods in particular, indicate that phosphate deposition was a cool-water, deeper ramp facies that transgressed over the carbonate bank twice, representing the Meade Peak and Retort Phosphatic Shale Members of the Phosphoria Formation.

Also, the single 'Pearlette ash' recognized by early workers now is known to be three different Pearlette family ash beds of greatly contrasting ages. The complexity of the stratigraphy, as it is currently understood, and the miscorrelations of early work necessitate abandonment of the archaic terms Kansan, Aftonian, and Nebraskan in stratigraphic terminology. Continued use of those terms will only promote confusion of stratigraphic nomenclature and erroneous correlations of stratigraphic units. The limited chronometric control available within the early and middle Pleistocene stratigraphic sequence is provided directly by dating or by correlation of buried soils and volcanic ash beds and it is provided inferentially by interpretation of magnetic polarity data. These controls provide, at best, a general time framework to begin a new synthesis of the Quaternary history of the region. New methods of dating are needed to facilitate long-distance correlation of early and middle Pleistocene deposits. ?? 1986.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Science Reviews","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"02773791","usgsCitation":"Hallberg, G., 1986, Pre-Wisconsin glacial stratigraphy of the central plains region in Iowa, Nebraska, Kansas, and Missouri: Quaternary Science Reviews, v. 5, no.

Major controls on base metal concentration are temperature, total chloride, and pressure. Higher temperature and higher chloride concentration favor higher metal solubilities as expected, but the pressure effect is opposite to that generally expected and is of considerable importance to the problem of ore mineral transport. At 500 °C, 0.5 kbar, and 1 m total chloride, Fe, Zn, and Pb solubilities were 8500, 4300, and 8700 ppm, respectively, whereas at 1 kbar they were 4200, 2400, and 2600 ppm, and at 2 kbar, 1700, 800, and 1200 ppm. The experimental results thus indicate that the metals could be carried over long distances on a decreasing pressure gradient so long as the temperature decreases were not sufficient to significantly offset the pressure effect. Such a condition could be approximated by a near-adiabatic transport cooling path. Such a condition is probably common geologically, especially for hydrothermal processes involving fairly deep-seated sources of heat and mineral components.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1986)14<377:EOPOOM>2.0.CO;2","issn":"00917613","usgsCitation":"Hemley, J., Cygan, G., and d’Angelo, W.M., 1986, Effect of pressure on ore mineral solubilities under hydrothermal conditions: Geology, v. 14, no. 5, p. 377-379, https://doi.org/10.1130/0091-7613(1986)14<377:EOPOOM>2.0.CO;2.","productDescription":"3 p.","startPage":"377","endPage":"379","numberOfPages":"3","costCenters":[],"links":[{"id":225327,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a05fbe4b0c8380cd5106b","contributors":{"authors":[{"text":"Hemley, J.J.","contributorId":59556,"corporation":false,"usgs":true,"family":"Hemley","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":368873,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cygan, G.L.","contributorId":56379,"corporation":false,"usgs":true,"family":"Cygan","given":"G.L.","email":"","affiliations":[],"preferred":false,"id":368872,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"d’Angelo, W.

All plutons show relatively radiogenic lead values for their ages and suggest the imprint of continental crustal sources especially in the coastal block and in central Maine. Plutons from the Connecticut Valley–Gaspé synclinorium allow for a more significant isotopic input from the subcontinental mantle. The three distinct lead-isotope groups probably identify plutons formed in different crustal fragments in a continental collisional environment that were juxtaposed after emplacement of the granites.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1986)14<322:LEFDSO>2.0.CO;2","issn":"00917613","usgsCitation":"Ayuso, R., 1986, Lead-isotopic evidence for distinct source of granite and for distinct basement in the northern Appalachians, Maine: Geology, v. 14, no. 4, p. 322-325, https://doi.org/10.1130/0091-7613(1986)14<322:LEFDSO>2.0.CO;2.","productDescription":"4 p.","startPage":"322","endPage":"325","numberOfPages":"4","costCenters":[],"links":[{"id":225253,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a45e0e4b0c8380cd674fe","contributors":{"authors":[{"text":"Ayuso, R.

Tested leach-methods purported to dissolve sulfide from silicate phases include: brominated water, brominated water-carbon tetrachloride, nitric-hydrochloric acid, hydrogen peroxide-ammonium citrate, bromine-methanol and hydrogen peroxide-ascorbic acid. Only the hydrogen peroxide-ammonium citrate method did not prove adequate in dissolving the sulfide phases. The remaining five methods dissolved the sulfide phases, but the indicated amount of attack on the silicate portion ranged from 3% to 100%.

The physical and mechanical properties of the shale were determined through use of core holes drilled to a maximum depth of 184 m.&nbsp;</span><i>In situ</i><span>&nbsp;borehole determinations included a gravimeter survey, pressuremeter testing, thermal profile measurements, and borehole velocity measurements. Onsite and offsite laboratory measurements included rebound measurements, sonic velocity measurements of shear and primary waves, X-ray mineralogy and major element determinations, size analyses, fracture analyses, fabric analyses, and determination of thermal properties.Below 15–22 m, the shale is an unweathered, saturated, overconsolidated, underpressured clay shale with a clay-mineral content ranging between 50 and 100%, dominantly composed of mixed-layer illitic smectites. The physical and mechanical properties vary widely. The variation is related to the clay mineral content (especially in bentonite zones), a large transverse mechanical anisotropy, and zones of fractures and microfractures, which may result from rebound caused by erosion. These may contribute to slope instability over large areas. The thermal and mechanical properties change markedly if the shale is permitted to dry out. The state of stress and overconsolidation appear to be functions of the depositional and erosional history of the deposit. Both are markedly affected by the large fracture zones.

The Gants-Cooke fault zone associated with the Jedburg basin in the 1886 meizoseismal area, an unnamed fault along the margin of the Branchville basin in the Bowman earthquake area and the offshore Helena Banks fault zone (no observed seismicity) along the margin of the Kiawah basin show evidence of reactivation of Triassic(? ) normal faults zones in a compressional, probably strike slip sense. The previously reported reverse separation of these faults observed on the seismic profiles in the late Cretaceous-Cenozoic Coastal Plain sediments is possibly produced by oblique slip with the horizontal component possibly 10 to 100 times the vertical. Earthquake recurrence intervals of several thousand years reported in the Charleston area appear consistent with ranges of magnitude of strike slip displacement inferred from the seismic reflection data, and are constrained by aeromagnetic data.","conferenceTitle":"Proceedings of the Third U.

The trends are characterized by increasing H2O and decreasing CO2 and sulfur. Maximum fumarole temperatures also show a linear decrease during this period. High-temperature fumarole gases collected from the crater and dome between September 1980 and July 1982 are all H2O-rich (> 90%) with 1-10% CO2 and small amounts of H2S, SO2, H2, CO, HC, and HF. Trace amounts of COS and S2 are present, and occasional observations of minor CH4 appear to result from contamination or low-temperature reactions in sample vessels. The O2 fugacities of the gases remain near Ni-NiO during cooling. The low sulfur content of the gases obviates the need for extensive gas-rock oxygen exchange to maintain fO2's near Ni-NiO. A detailed thermodynamic analysis of 50 gas samples collected between September 1980 and December 1981 led to improved compositions for 22 samples. The gases were initially in a state of equilibrium, but disequilibrium modifications from atmospheric oxidation of H2 and, to a lesser extent, CO occurred within the upper portions of the fumarole vents. The last temperatures of equilibrium for the fumarole gases range from 800??C to 650??C and are nearly always higher than the collection temperatures. No evidence was found of disequilibrium admixture of surface waters; if such modifications of the fumarole gases occurred, the water must have been added at depth and have reequilibrated with the other gas species at magmatic or near-magmatic temperatures. The highest quality analytical data are obtained by field gas chromatograph measurements and from caustic soda bottle samples. Samples collected in evacuated bottles or by pumping through double stopcock tubes tend to be severely deficient in sulfur due to post-collection reactions between H2S and SO2. It is also necessary to infer the water content of the latter samples. ?? 1986.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Gerlach, T., and Casadevall, T.J., 1986, Evaluation of gas data from high-temperature fumaroles at Mount St. Helens, 1980-1982: Journal of Volcanology and Geothermal Research, v. 28, no. 1-2, p. 107-140.","startPage":"107","endPage":"140","numberOfPages":"34","costCenters":[],"links":[{"id":223580,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c77e4b0c8380cd52b6f","contributors":{"authors":[{"text":"Gerlach, T.M.","contributorId":38713,"corporation":false,"usgs":true,"family":"Gerlach","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":370007,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Casadevall, T.

In the second step, evaluation of alternative methods of providing streamflow information, flow-routing models, and regression models were developed for estimating daily flows at 251 stations of the 3,493 stations analyzed. In the third step of the analysis, relationships were developed between the accuracy of the streamflow records and the operating budget. The existing streamgaging networks in four Districts were further analyzed to determine the impacts that satellite telemetry would have on the cost effectiveness. Satellite telemetry was not found to be cost effective on the basis of hydrologic-data collection alone, given present cost of equipment and operation.","conferenceTitle":"Preprinted Proceedings of the 4th International Conference on River Basin Management.","conferenceLocation":"Sao Paolo, Braz","language":"English","publisher":"Int Assoc on Water Pollution Research & Control","publisherLocation":"London, Engl","usgsCitation":"Scott, A.G., 1986, ANALYSIS OF THE U.

The proximity of the dolomite aquifer to the land surface makes it susceptible to contamination from man 's activities. Water from the aquifer was analyzed and several characteristics were monitored in a 30-sq-mi area of Waukesha County, including: water temperature, calcium, magnesium, potassium, strontium, alkalinity, chlorides, fluorides, sulfates, nitrites, nitrates, nitrogen, iron, manganese, hardness, and pH.</p><p>The water is hard, commonly having a hardness of more than 350 mg/L as CaCO<sub>3</sub>, and high in iron, commonly containing more than 0.3 mg/L. However, nutrient concentrations are not high; nitrogen, greater than 8 mg/L; phosphorus, none detected; and potassium, greater than 4 mg/L. The chloride content of the water averages more than 50 mg/L indicating contamination probably from septic systems. The water quality varies over a time. High concentrations of chloride and, occasionally, of bacteria correlate with periods of groundwater recharge over a period of 17 months.

The Lloyd aquifer is virtually untapped throughout most of central Long Island because current legal restrictions permit its use only in coastal areas. The upper surface of the Lloyd aquifer ranges in depth from 100 ft below land surface on the north shore to more than 1,500 ft on the south shore. Aquifer thickness increases southward from 50 ft to about 500 ft. Transmissivity ranges from 1,500 to 19,000 sq ft/day. All recharge (35 to 40 mil gal/day) and nearly all discharge is through the overlying confining unit. Nearly all of the pumpage (approximately 20 mil gal/day) is in Queens and along the north and south shores of Nassau County. Potable water can be obtained on most of Long Island in larger quantities and at shallower depths from other aquifers than from the Lloyd. Local contamination of these other aquifers, however, may require at least temporary withdrawals from the Lloyd in noncoastal areas. Significant withdrawals from the Lloyd aquifer may lower the potentiometric surface and thereby induce landward movement of sea water into the aquifer in coastal areas.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri854159","usgsCitation":"Garber, M.S., 1986, Geohydrology of the Lloyd aquifer, Long Island, New York: U.S. Geological Survey Water-Resources Investigations Report 85-4159, iv, 36 p., https://doi.org/10.3133/wri854159.","productDescription":"iv, 36 p.","costCenters":[],"links":[{"id":415547,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_36316.htm","linkFileType":{"id":5,"text":"html"}},{"id":123386,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1985/4159/report-thumb.jpg"},{"id":56103,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1985/4159/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"New York","otherGeospatial":"Lloyd aquifer, Long Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -72.51130360165777,\n              41.04897322161665\n            ],\n            [\n              -74.05971240699634,\n              41.04897322161665\n            ],\n            [\n              -74.05971240699634,\n              40.51344467382111\n            ],\n            [\n              -72.51130360165777,\n              40.51344467382111\n            ],\n            [\n              -72.51130360165777,\n              41.04897322161665\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a894a","contributors":{"authors":[{"text":"Garber, M.

The need for current land-cover information in Alaska comes principally from the mandates of the Alaska National Interest Lands Conservation Act (ANILCA), December 1980, which requires major land management agencies to prepare comprehensive management plans. The land-cover mapping projects integrate digital Landsat data, terrain data, aerial photographs, and field data. The resultant land-cover and terrain maps and associated data bases are used for resource assessment, management, and planning by many Alaskan agencies including the U.S. Fish and Wildlife Service, U.S. Forest Service, Bureau of Land Management, and Alaska Department of Natural Resources. Applications addressed through use of the digital land-cover and terrain data bases range from comprehensive refuge planning to multiphased sampling procedures designed to inventory vegetation statewide. The land-cover mapping programs in Alaska demonstrate the operational utility of digital Landsat data and have resulted in a new land-cover mapping program by the USGS National Mapping Division to compile 1:250,000-scale land-cover maps in Alaska using a common statewide land-cover map legend.</p>","language":"English","publisher":"American Society for Photogrammetry and Remote Sensing","usgsCitation":"Shasby, M., and Carneggie, D.M., 1986, Vegetation and terrain mapping in Alaska using Landsat MSS and digital terrain data: Photogrammetric Engineering and Remote Sensing, v. 52, no. 6, p. 779-786.","productDescription":"8 p.","startPage":"779","endPage":"786","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":298340,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -179.736328125,\n              50.401515322782366\n            ],\n            [\n              -179.736328125,\n              71.7188822971392\n            ],\n            [\n              -141.064453125,\n              71.7188822971392\n            ],\n            [\n              -141.064453125,\n              50.401515322782366\n            ],\n            [\n              -179.736328125,\n              50.401515322782366\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"52","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54fec43fe4b02419550debf2","contributors":{"authors":[{"text":"Shasby, Mark shasbym@usgs.gov","contributorId":223,"corporation":false,"usgs":true,"family":"Shasby","given":"Mark","email":"shasbym@usgs.gov","affiliations":[],"preferred":false,"id":541960,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carneggie, David M.","contributorId":62758,"corporation":false,"usgs":true,"family":"Carneggie","given":"David","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":541961,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The sample used was from Santa Barbara Basin (off southern California) and is typical of fine‐grained marine sediments: it is a clayey silt with a common suite of minerals and other constituents. During the experiment, texture and composition (except organic content) were constant; only the quantity of natural, indigenous organic matter was changed.</p>\n<p>&nbsp;</p>\n<p>A strong linear relationship exists between the independent variable, the amount of organic carbon present in the sample, and the dependent variables. Liquid limit, plastic limit, and plasticity index all increased with increasing organic content over the range studied (0.57&ndash;3.20% organic carbon). Grain‐specific gravity decreased. All had linear correlation coefficients (<i>r</i>) greater than |0.90| and&nbsp;<i>r</i>&nbsp;<sup>2</sup>&nbsp;values greater than 90%, except the plasticity index (83%).</p>\n<p>&nbsp;</p>\n<p>Comparing the results of regression analyses from this and several similar studies shows that although there is good qualitative agreement, there are quantitative inconsistencies. In particular there is considerable overall variability in the regression coefficients. Among studies on marine sediments the inconsistencies are less pronounced, yet still evident. The increase in liquid limit as organic carbon increased by 1 % sediment dry weight ranged from 9 to 28% water content; in the plastic limit the range was from 4 to 18%. However, in these marine studies regression coefficients are relatively close in value in some cases, levels of significance of the regressions are high in most cases, and in all cases the relationships appear to be linear over the range of organic carbon percentage studied. Finally, we believe that a relatively clear relationship between plasticity and organic carbon begins to emerge when the latter exceeds a value of 2%.</p>","language":"English","publisher":"Taylor and Francis","doi":"10.1080/10641198609388191","usgsCitation":"Taylor and Francis, 1986, A note on the relationships between organic matter and some geotechnical properties of a marine sediment: Marine Geotechnology, v. 6, no. 3, p. 281-297, https://doi.org/10.1080/10641198609388191.","productDescription":"17 p.","startPage":"281","endPage":"297","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":296987,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2b1ee4b08de9379b3259"}
