Geochemical prospecting for Carlin-type gold deposits
Sherman P. Marsh
1976, Open-File Report 76-335
Disseminated, Carlin-type, gold deposits are associated with a volatile suite of elements consisting of Hg, As, Sb, W, and sometimes, but not always, Au. Geochemical exploration for this type of disseminated deposit depends upon recognizing the significance of this volatile suite and interpreting it in light of other geologic and...
Distribution of seed plants with respect to tide levels and water salinity in the natural tidal marshes of the northern San Francisco Bay Estuary, California
Brian F. Atwater, Charles W. Hedel
1976, Open-File Report 76-389
Shoaling of subtidal and intertidal mud flats has permitted tidal marshes to spread across large marginal areas of the San Francisco Bay estuary during the past several thousand years. By 1850 A.D. the tidal marshes of the estuary, including those of the Sacramento - San Joaquin Delta, covered an area...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Iliamna, Lake Clark, Lime Hills, and McGrath quadrangles, Alaska
Edward Huntington Cobb
1976, Open-File Report 76-485
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Iliamna, Lake Clark, Lime Hills, and McGrath quadrangles, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Fairbanks Quadrangle, Alaska
Edward H. Cobb
1976, Open-File Report 76-662
For each mineral occurrence there is a page that gives the name of the occurrence; the mineral commodities present (listed alphabetically for metallic commodities and then for nonmetallic commodities); the mining district (Ransome and Kerns, 1954) in which the occurrence is located; the name of the 1:250,000-scale topographic quadrangle (Fairbanks);...
Use of an airborne Fraunhofer line discriminator for the detection of solar stimulated luminescence
Robert D. Watson, William R. Hemphill
1976, Open-File Report 76-202
Luminescence is the property of some materials to emit light when excited by external stimuli such as ultraviolet or visible light or by chemical or mechanical action. The Fraunhofer line discriminator (FLO) is an airborne electro-optical device which operates as a non-imaging radiometer and permits detection of solar stimulated luminescence...
Water availability, quality, and use in Alaska
G. O. Balding
1976, Open-File Report 76-513
The Alaska Water Assessment, sponsored by the Water Resources Council, is a specific problem analysis for Alaska of the National Assessment of Water and Related Land Resources. The assessment addresses water and water-related land problems, present and future. It was felt that a supplementary report, as a part of the...
Crossbedding of the Potomac Formation in Fairfax County, Virginia
Gordon Whitney Weir
1976, Open-File Report 76-193
Crossbedding in sandstone units is the most conspicuous sedimentary structure of the Potomac Formation in Fairfax County, Virginia. Most sets of crossbeds are a few feet thick and several feet wide and tens of feet long. Trough sets are dominant, but planar sets are also common. Dip directions of crossbeds...
