Land use and land cover, 1972-77, Culpeper Basin, Virginia-Maryland
Water Resources Division, U.S. Geological Survey
1980, Miscellaneous Field Studies Map 1208
Land use refers to man's activities that relate directly to the land.  Lover cover describes the land surface- vegetation, water, naturally- occurring soil and rock, and artificial constructions. In showing land use and land cover in the Culpeper Basin, this map features a consistent level of detail and standardization of categories....
Reconnaissance of polychlorinated biphenyls in the Arkansas River between Muskogee and Webbers Falls lock and dam, Oklahoma
J.D. Stoner
1980, Open-File Report 80-216
Analysis of samples collected from the Arkansas River between Muskogee and Webbers Falls Lock and Dam, Oklahoma, in November 1978 showed that concentrations of polychlorinated biphenyls in the dissolved and suspended phases were less than the detection limit of 0.1 micrograms per liter. The maximum polychlorinated biphenyl concentration measured in...
Integrated uranium system in the Marysvale volcanic field, west-central Utah
Thomas August Steven, Charles G. Cunningham, Michael N. Machette
1980, Open-File Report 80-524
Uranium in the Marysvale volcanic field is known to occur in several geologic environments, and is hypothesized to occur in others. Together the known and hypothetical occurrences range from a source in rhyolite magma, through porphyry-type deposits, hydrothermal vein deposits, dispersed hydrothermal deposits, and after transport in ground and surface...
Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona
R. B. Tripp, H. N. Barton, J.C. Negri, P. K. Theobald
1980, Miscellaneous Field Studies Map 1162-E
Reconnaissance geochemical and mineralogical sampling was done in the Sierra Ancha Wilderness and Salome Study Area during April and May 1978. This map shows the distribution of chalcopyrite, florite, galena, scheelite, and lead-rich iron oxides in the nonmagnetic fraction of the heavy-mineral concentrate of stream sediment samples collected during the...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1980
John B. Townshend, J.E. Papp, E.A. Sauter, S.P. Tilton
1980, Open-File Report 80-300-B
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Estimated water use in Florida, 1977
Stanley D. Leach, Henry G. Healy
1980, Water-Resources Investigations Report 79-112
During 1977, an average of 21,466 million gallons of water was withdrawn daily for use in Florida--an increase of 6,153 million gallons per day since 1970. The 1977 daily use was 14,812 million gallons of saline water and 6,654 million gallons of freshwater. Most of the saline water, largely surface...
