Preliminary residual magnetic map of the eastern Bering Shelf and parts of western Alaska
Kimberly A. Bailey, Alan K. Cooper, Michael S. Marlow, David W. Scholl
1976, Miscellaneous Field Studies Map 716
Residual magnetic anomalies for the offshore data were calculated by subtracting the Earth's main dipole field, adjusted for secular variations (based on the International Geomagnetic Reference Field (IGRF), epoch 1965, Fabiano and Peddie, 1969), from the observed values of the surveys listed below. The effects of diurnal variations and magnetic...
Geochemical maps showing the distribution and abundance of tin in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. M. O’Leary, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-K
This series of geochemical maps shows the distribution of tin in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized geology...
Maps showing mineralogical and geochemical data for heavy-mineral concentrates in the Tanacross quadrangle, Alaska
R. B. Tripp, G.C. Curtin, G.W. Day, R. C. Karlson, S.P. Marsh
1976, Miscellaneous Field Studies Map 767-O
This series of maps showing the following data for heavy mineral concentrates: distribution and abundance of selected ore-related minerals, distribution and abundance of copper in the magnetic fraction, and distribution and abundance of lead, copper, tin, beryllium, tungsten and bismuth in the nonmagnetic fraction. The data are plotted on base...
Map of coal-mining features, Allegheny County, Pennsylvania
W.E. Davies, J. S. Pomeroy, W. R. Kohl
1976, Miscellaneous Field Studies Map 685-C
This map is one result of a series of studies sponsored by the Appalachian Regional Commission as part of a larger U.S. Geological Survey program of environmental analysis of a part of southwestern Pennsylvania. The map summarizes surface features resulting from coal mining. The distribution of surface features is largely...
Geochemical maps showing the distribution and abundance of arsenic and mercury in the Tanacross Quadrangle, Alaska
G.C. Curtin, R. M. O’Leary, R.B. Carten
1976, Miscellaneous Field Studies Map 767-J
This series of geochemical maps shows the distribution of arsenic and mercury in the minus-80-mesh stream sediment and of arsenic in the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level. The geochemical data are plotted on a base map that shows generalized geology and...
Water resources data for California, water year 1975; Volume 3: Southern Central Valley Basins and The Great Basin from Walker River to Truckee River
Water Resources Division, U.S. Geological Survey
1976, Water Data Report CA-75-3
Water-resources data for the 1975 water year for California consist of records of streamflow and contents of reservoirs at gaging stations, partial-record stations, and miscellaneous sites; records of water quality including the physical, chemical, and biological characteristics of surface and ground water; and records of water levels in selected observation...
Geochemical maps showing the distribution and abundance of molybdenum in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R.B. Carten, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-G
This series of geochemical maps shows the distribution of molybdenum in 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 organic and inorganic material) collected beneath the water level, and (D) the ash of...
