Ground water is a valuable resource often used for industry, commerce, agriculture, and drinking water. In the 19080's, ground water provided 35 percent of the municipal water supplies in the United States and 95 percent of the rural, domestic drinking water. Scientists participating in ground-water studies may determine the...
Coal geology of the Paleocene-Eocene Calvert Bluff Formation (Wilcox Group) and the Eocene Manning Formation (Jackson Group) in east-central Texas: Field trip guidebook for the Society for Organic Petrology, Twelfth Annual Meeting, The Woodlands, Texas, August 30, 1995

This report is designed to summarize the current knowledge of the talc deposits and includes locations and descriptions of occurrences in 27 states, with emphasis...
Preliminary Geologic Map of the Big Pine Mountain Quadrangle, California
J. G. Vedder, Hugh McLean, R. G. Stanley
1995, Open-File Report 95-554
Reconnaissance geologic mapping of the San Rafael Primitive Area (now the San Rafael Wilderness) by Gower and others (1966) and Vedder an others (1967) showed s number of stratigraphic and structural ambiguities. To help resolve some of those problems, additional field work was done on parts of the Big Pine...
Land-cover sampling designs, data-collection procedures, and land-cover data for the Central Nebraska Basins, 1993-94
R. B. Zelt, J. T. Dugan, M.S. Kelley
1995, Open-File Report 95-166
Within the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program, land-cover data are used in characterizing drainage areas upstream from surface-water sampling sites and areas selected for spatially distributed ground-water sampling. During the period of time when the initial 20 NAWQA study study-unit investigations were evaluating existing land-cover data, a...

Estimating heat capacity and heat content of rocks
Eugene C. Robertson, Bruch S. Hemingway
1995, Open-File Report 95-622
New heat-capacity measurements are reported for four rock types; Westerly granite from Bradford, RI, andesite from Lake County, OR, peridotite from Sonoma County, CA, and basalt from the Columbia River Group. Measurements were made on powders of the rocks in the temperature range of 340 to about 1000 K. Our measured...
