Analysis of borehole geophysical information across a uranium deposit in the Jackson Group, Karnes County, Texas
Jeffrey J. Daniels, James Henry Scott, Bruce D. Smith
1979, Open-File Report 79-585
Borehole geophysical studies across a uranium deposit in the Jackson Group, South Texas, show the three geochemical environments often associated with uranium roll-type deposits: an altered (oxidized) zone, an ore zone, and an unaltered (reduced) zone. Mineralogic analysis of the total sulfides contained in the drill core shows only slight...
Reconnaissance evaluation of surface-water quality in Eagle, Grand, Jackson, Pitkin, Routt, and Summit Counties, Colorado
Linda J. Britton
1979, Open-File Report 79-420
Water-quality data were collected from streams in a six-county area to determine if the streams were polluted and, if so, to determine the sources of the pollution. Eighty-three stream sites were selected for sampling in Eagle, Grand, Jackson, Pitkin, Routt, and Summit Counties. Also included are data from 28 sites...

Possible reestablishment of sawtimber production following mining in the Osceola National Forest, an analysis of the state-of-the-art, February 9, 1978
J. Scott Boyce
1979, Open-File Report 79-524
There is a good possibility that sawtimber production could be reestablished on the Osceola National Forest. Engineering technology that is coming on-line should allow the establishment of land/water relationships that meet the requirements of desired tree species. Information available on soil-plant relationships indicate an absence of phytotoxic materials in various...

General geology and mines of the East Tintic mining district, Utah and Juab counties, Utah, with sections on the geology of the Burgin mine and the geology of the Trixie mine
H. T. Morris, Thomas Seward Lovering, A. P. Mogensen, W.M. Shepard, L. I. Perry, S. M. Smith
1979, Professional Paper 1024
This report is a study of the rocks, geologic structures, and mines of a highly productive silver, gold, and base-metal mining district in the east-central Great Basin. The East Tintic mining district is in the east-central part of the East Tintic Mountains, near the east margin of the Basin and...

A uranium occurrence in the Tertiary Kootznahoo Formation on Kuiu Island, southeast Alaska
Kendell A. Dickinson
1979, Open-File Report 79-1427
Radioactive anomalies as high as 50 times background and uranium-bearing samples were discovered in parts of the nonmarine Tertiary Kootznahoo Formation in southeast Alaska by K. A. Dickinson and John Mitchell. Samples containing as much as 1300 ± 400 ppm uranium, measured by beta eU, were found. These samples have...

1979, Open-File Report 79-1463
Measurements of the helium concentration of soil samples collected and stored in Vacutainer-brand evacuated glass tubes show that Vacutainers are reliable containers for soil collection. Within the limits of reproducibility, helium content of soils appears to be independent of variations in soil temperature, barometric pressure, and quantity of soil moisture...
Terrain corrections for borehole and tower gravity measurements
Larry A. Beyer
1979, Open-File Report 79-721
Many investigators have computed terrain corrections for gravity measurements made in vertical mine shafts (e.g., Rogers, 1952; Domzalski, 1954; Rische, 1957; Vaschilov, 1964) and on structures above ground (e.g., Hammer, 1938; Kumagai et al., 1960; Kuo et al., 1969; Fajklewicz, 1976). The need for a rapid method for calculating terrain...

Additional water for irrigation is needed by the Santa Rosa Indian Reservation, Riverside County, California. Water in the area is derived from precipitation, which averages 12 inches annually, on three subbasins nearly surrounding the 17-square-mile reservation. No ground water flows in from outside the area. A supply well that taps...
