Douglas P. Klein
1983, Open-File Report 83-443
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....
Habitat Suitability Index Models: Longnose sucker
Elizabeth A. Edwards
1983, FWS/OBS 82/10.35
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Longnose sucker (Catostomus catostomus), a freshwater fish. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater areas of the continental...

Quality of ground water in southern Buchanan County, Virginia
Stanley M. Rogers, John D. Powell
1983, Water-Resources Investigations Report 82-4022
In seven small contiguous stream basins in the coal area of southwest Virginia, ground water is predominantly bicarbonate in anion composition, with calcium as the major cation in the ridges and sodium the major cation in the lower altitudes. Sulfate is the major anion in water associated with coal seams...

Water quality of the Potomac River at Chain Bridge at Washington, D.C.; hydrologic-data report, 1978 water year
Stephen F. Blanchard
1983, Open-File Report 83-147
Water quality data are presented, measured at the Potomac River at Chain Bridge at Washington, D.C. for the 1978 water year. Samples were generally collected twice a week and more frequently during periods of high flow. The samples were analyzed for nitrogen, phosphorus, silica and suspended sediments. (USGS)...
Distribution of trace elements in drilling chip samples around a roll-type uranium deposit, San Juan Basin, New Mexico
H.C. Day, C.S. Spirakis, R. S. Zech, A. R. Kirk
1983, Open-File Report 83-56
Chip samples from rotary drilling in the vicinity of a roll-type uranium deposit in the southwestern San Juan Basin were split into a whole-washed fraction, a clay fraction, and a heavy mineral concentrate fraction. Analyses of these fractions determined that cutting samples could be used to identify geochemical halos associated...

The international phosphate resource data base; development and maintenance
Nancy J. Bridges
1983, Open-File Report 83-490
The IPRDB (International Phosphate Resource Data Base) was developed to provide a single computerized source of geologic information about phosphate deposits worldwide. It is expected that this data base will encourage more thorough scientific analyses of phosphate deposits and assessments of undiscovered phosphate resources, and that methods of data collection...

Sources and mechanisms of recharge for ground water in the west-central Amargosa Desert, Nevada– A geochemical interpretation
H.C. Claassen
1983, Open-File Report 83-542
Ground water in the west-central Amargosa Desert, Nevada, was recharged primarily by overland flow of snowmelt in or near the present-day stream channels, rather than by subsurface flow from highland recharge areas to the north. Geochemical arguments, including reaction mechanisms, are used to support these findings. Carbon-, hydrogen-, and oxygen-isotope...
