Al Kushaymiyah as a target for a Colorado-type molybdenite deposit
P. K. Theobald
1971, Open-File Report 71-281
The granitic complex in the vicinity of Al Kushaymiyah was singled out by Whitlow (19,69, 1969a, 1971), as one of the most promising areas for exploration in the Southern Wajd quadrangle (Jackson and others, 1962). He noted in particular the intensity of shattering and silicification of these potassium-rich granites, and...

This report was prepared to illustate the locations and lunar orientations of the documented samples returned by Apollo 14. It supersedes U.S. Geological Survey Interagency Report No. 27 (Swann et al., 1971a). Some of the illustrations are taken from the Preliminary Science Report ("Ninety-day report") submitted to the National Aeronautics...
Ground-water hydrology of the San Pitch River drainage basin, Sanpete County, Utah
Gerald B. Robinson Jr.
1971, Water Supply Paper 1896
The San Pitch River drainage basin in central Utah comprises an area of about 850 square miles; however, the investigation was concerned primarily with the Sanpete and Arapien Valleys, which comprise about 250 square miles and contain the principal ground-water reservoirs in the basin. Sanpete Valley is about 40 miles...

1971, Open-File Report 71-138
Electronic computer studies were made on a suite of 815 chemical analyses of soluble salines in nitrate ores, representing monthly averages of ores treated by the two largest nitrate plants in Chile from 1932 to 1967. A package statistical program, STATPAC, of the U.S. Geological Survey was utilized: 1) to...

The national hydrologic bench-mark network
Ernest D. Cobb, J.E. Biesecker
1971, Circular 460-D
The United States is undergoing a dramatic growth of population and demands on its natural resources. The effects are widespread and often produce significant alterations of the environment. The hydrologic bench-mark network was established to provide data on stream basins which are little affected by these changes. The network is...

In a recent article in "Science" discussing the Environmental Policy Act of 1969, Gillette (1971) states "The law's instructions for preparing an impact report apparently are not specific enough to insure that an agency will fully, or even usefully, examine the environmental effects of the projects it plans." This report...
