Integration of geological remote-sensing techniques in subsurface analysis
James V. Taranik, Charles M. Trautwein
1976, Open-File Report 76-402
Geological remote sensing is defined as the study of the Earth utilizing electromagnetic radiation which is either reflected or emitted from its surface in wavelengths ranging from 0.3 micrometre to 3 metres. The natural surface of the Earth is composed of a diversified combination of surface cover types, and geologists...
Distribution and abundance of arsenic in bedrock, mineralized, vein, and altered rock samples, McCarthy quadrangle, Alaska
Keith Robinson, C. M. McDougal, R. M. O’Leary, Theodore Billings
1976, Miscellaneous Field Studies Map 773-M
A geochemical survey was conducted in the McCarthy quadrangle Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for arsenic from 827 rock samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976...
Distribution and abundance of lead in stream sediments and moraine debris, McCarthy Quadrangle, Alaska
Keith Robinson, C. M. McDougal, G.W. Day, Theodore Billings
1976, Miscellaneous Field Studies Map 773-G
A geochemical survey was conducted in the McCarthy quadrangle, Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for lead, from 1,453 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...
Water and stream-sediment sampling techniques for use in uranium exploration
Karen J. Wenrich-Verbeek
1976, Open-File Report 76-77
Methods of sampling water and stream sediments for uranium were established in this study. Water samples should be taken using a US DH-48 water sampler across the stream channel and should be filtered and acidified in situ. Stream sediments should be taken as a composite sample up and across the...
Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska
Gary R. Winkler, Hugh McLean, George Plafker
1976, Open-File Report 76-198
Petrographic examination of 74 outcrop samples of Paleocene through Pliocene age from the onshore Gulf of Alaska Tertiary Province indicates that sandstones of the province characteristically are texturally immature and mineralogically unstable. Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings...
Composite geochemical map of anomalous copper and molybdenum distribution in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-M
This geochemical map delineates drainage basins in which either anomalous copper, molybdenum, or both copper and molybdenum were detected in at least one of four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed...
Annotated bibliography of the lakes, ponds, and reservoirs of New York State through 1974 (exclusive of lakes Erie and Ontario)
1976, Water-Resources Investigations Report 76-55
More than 1,200 titles and abstracts of limnological studies of ponds, reservoirs, and lakes (excluding Lakes Erie and Ontario) are compiled in one volume. Publications cited date from the late 19th century through 1974. Titles and abstracts are presented alphabetically by author's name; cross indexes of coauthors, locations, and subjects...
Mineral resources of Elko County, Nevada
Roscoe Maurice Smith
1976, Open-File Report 76-56
Of the 66 named mining districts in Elko County, 56 have been productive of one or more of 19 different commodities: 11 metals--copper, gold, silver, lead, zinc, mercury, tungsten, manganese, iron, uranium, and antimony; 8 nonmetals--sand and gravel, stone, barite, diatomite, gems, oil shale, volcanic ash, and clay. In addition...
