Distribution of gold, tellurium, silver, and mercury in part of the Cripple Creek district, Colorado
Garland Bayard Gott, J. H. McCarthy, G.H. Van Sickle, J. B. McHugh
1967, Circular 543
Geochemical exploration studies were undertaken in the Cripple Creek district to test the possibility that large low-grade gold deposits might be found. Surface rock samples taken throughout the district indicate that the volcanic rocks between the productive veins contain an average of about 0.6 ppm (part per million) gold. In...
Geohydrology of the Souris River Valley in the vicinity of Minot, North Dakota
Wayne A. Pettyjohn
1967, Water Supply Paper 1844
The Minot area is in the north-central part of North Dakota and includes part of the Souris River valley. The region is covered by glacial drift of late Wisconsin age except in small areas where the Fort Union Formation of Tertiary age crops out. Thickness of the drift is controlled...
Development of ground-water supplies at Mississippi test facility, Hancock County, Mississippi
Roy Newcome
1967, Water Supply Paper 1839-H
Potable and industrial water supplies at the National Aeronautics and Space Administration's Mississippi Test Facility in Hancock County, Miss., are obtained from large-capacity wells that tap southward-dipping water-bearing sands of Miocene and Pliocene age. The fresh-water-bearing section is 2,000-3,000 feet thick in the area, and individual aquifers are as thick...
Summary of hydrologic and physical properties of rock and soil materials, as analyzed by the hydrologic laboratory of the U.S. Geological Survey, 1948-60
D. A. Morris, A.I. Johnson
1967, Water Supply Paper 1839-D
The Hydrologic Laboratory was established in 1948 to serve as the central testing laboratory for the Water Resources Division of the U.S. Geological Survey. Since then, thousands of samples of rock and soil materials have been analyzed in the laboratory. Analytical data on samples from 42 States and for the...
Preliminary geologic section from Pahute Mesa, Nevada Test Site, to Enterprise, Utah
P. J. Barosh
1967, Open-File Report 67-11
The 154-mile long geologic cross section trends nearly perpendicular to the structural grain of the Basin-Range province in Nevada, and in Utah extends eastward into the transition zone between the Basin-Range and Colorado Plateau provinces. The structure is characterized by complex thrust: faults, involving uppermost Precambrian to lower Mesozoic sedimentary...
