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...
Geochemical, aeromagnetic, and generalized geologic maps showing distribution and abundance of lead and silver, Golconda and Iron Point quadrangles, Humboldt County, Nevada
R. L. Erickson, S.P. Marsh
1971, Miscellaneous Field Studies Map 315
Detailed geologic and geochemical studies of the four 7 1/2-minute quadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun during the 1969 summer field season. The objectives of the project are to map the geology of this struct urally complex area at 1:24·,000 scale...
Geochemical, aeromagnetic, and generalized geologic maps showing distribution and abundance of mercury and arsenic, Golconda and Iron Point quadrangles, Humboldt County, Nevada
R. L. Erickson, S.P. Marsh
1971, Miscellaneous Field Studies Map 312
Detailed geologic and geochemical studies of the four 7 1/2-minute wuadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun druring the 1969 summer field season. The objectives of the project are to map the geology of this structurally complex area at 1:24,000 scale and to...
Classification of natural ponds and lakes in the glaciated prairie region
Robert E. Stewart, Harold A. Kantrud
1971, Resource Publication 92
The wetland classification system for the United States adopted by the Bureau of Sport Fisheries and Wildlife in 1953 is described by Martin et al (1953) and by Shaw and Fredine (1956).  That classification has been followed by many biologists in recent years and is especially useful in categorizing in...
Mathematical ground-water model of Indian Wells Valley, California
R. M. Bloyd Jr., S. G. Robson
1971, Open-File Report 72-41
A mathematical model of the Indian Wells Valley ground-water basin was developed and verified. The alternating-direction implicit method was used to compute the mathematical solution. It was assumed that there are only two aquifers in the valley, one being deep and the other shallow. Where the shallow aquifer occurs, the...
