Pliocene intrusive rocks and mineralization near Rico, Colorado
Charles W. Naeser, C. G. Cunningham, R. F. Marvin, J. D. Obradovich
1979, Open-File Report 79-1093
Fission-track and potassium-argon studies of intrusive rocks in the vicinity of Rico, Colorado, have shown that at least two periods of igneous activity occurred and that significant ore mineralization is associated with alaskites and latites that are 3 to 5 million years old. Discordant fission-track ages of apatite and zircon...

1979, Open-File Report 79-1163
The lower Dirty Devil River basin area in southeastern Utah has an area of about 4,300 square miles (11,1140 square kilometers) and ranges in altitude from about 3,700 to more than 11,000 feet (1,130 to 3,350 meters) above mean sea level. Precipitation, the main source of water in the area,...

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...
Hydrologic data, 1974-77, Stovepipe Wells Hotel area, Death Valley National Monument, Inyo County, California
Charles Edwin Lamb, D.J. Downing
1979, Open-File Report 79-203
Ground-water levels in most wells did not change significantly from 1974 to 1977 in the Stovepipe Wells Hotel area. The average water-level decline was less than 0.10 foot between August 1974 and August 1977 in 10 observation wells. Water-level contours show a depression centered on the two pumping wells, but...

New geologic, ground magnetic, E-mode VLF, and radiometric surveys at Phillips Mine-Camp Smith uranium prospect, Westchester and Putnam Counties, New York
David L. Campbell, Richard I. Grauch, Connie J. Nutt
1979, Open-File Report 79-1078
This report updates U.S. Geological Survey Open-File Report 77-780 by including new field data taken in July 1978. A revised geologic map is included, as are new geophysical data from an approximately 0.3-km by 0.5-km area just northeast of and adjoining the area surveyed earlier. The pattern which had been...
