Abstract: This report is a synthesis of published and unpublished data on the rocks of the Anadarko basin.

From introduction: This report summarizes the basic information that has been collected on 49 wells and test holes in the Nevada Test Site, together with information on 9 springs.

From abstract: The U.S. Atomic Energy Commission, through the Office of Test Operations, Albuquerque Operations Office, plans to detonate a nuclear device in a massive salt bed 1,200 feet beneath the land surface. The project, known as Project Gnome, is an element of the Plowshare program--a study of peacetime applications of nuclear fission. The location of the proposed underground shot is in a sparsely-populated area in southeastern Eddy County, N. Mex., east of the Pecos River and about 25 miles southeast of the city of Carlsbad.

From introduction: The geologic studies in the Ul2e.03a and Ul2e.03b tunnels were conducted as part of the Geological Survey's investigations for the Vela Uniform program, Project Shade, and were completed for the purpose of 1) determining the preshot lithologic, structural, and chemical and physical properties of the tuffs exposed in the tunnels for comparison wits postshot geologic data, and 2) evaluating these data in order to predict the geologic effects of the planned nuclear explosion at tie end of the tunnels.

From introduction: The geologic studies in the U12b.08 tunnel were conducted by the U. S. Geological Survey on behalf of the U. S. Atomic Energy Commission for the purpose of determining the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel. These data will be used in evaluating the geologic effects of the explosion by comparison with similar post-shot geologic data.

The following report covers potentiometric studies with hydrogen-sensitive and cation-sensitive glass electrodes supplemented by chemical determinations and X-ray diffractions on a hydrogen-montmorillonite. These studies indicate that the clay behaves as a mixture of two acids, resulting from the presence of interlayer and edge exchange sites, both occupied by hydrogen ions.

Analysis of geologic, hydrologic, and geophysical data obtained in and around Yellow Creek core hole No. 1, Rio Blanco County, Colorado, indicate a 1,615-foot section of oil shale was penetrated by the hole. Geophysical log data indicate the presence of 25 gallons per ton shale for a thickness of 500 feet may be marginal. The richest section of oil shale is indicated to be centered around a depth of 2,260 feet. Within the oil shale the interval 1,182 to 1,737 feet is indicated to be relatively structurally incompetent and probably permeable. Extension of available regional hydrologic data indicate the oil shale section is probably water bearing and may yield as much as 1,000 gallons per minute. Hydrologic testing in the hole is recommended.
