The following report covers the study of a small composite stock at Oak Spring, Nevada, known as Climax granite to study the seismic effect of a deep nuclear explosion contained in a large volume of unfractured rock.

A report outlining the geology of the U12i and U12i.01 tunnels and the lithology of the U12i.01 drill hole, located at a Nevada test site. Prepared on behalf of the U.S. Atomic Energy Commission.

From introduction: The general objectives of this Geological Survey were to study the geologic and geophysical studies of the effects of underground nuclear explosions under Rainier Mesa.

Abstract: As a part of continuous geologic and geophysical investigations at the Nevada Test Site, gamma-radioactivity measurements are being made in tunnels and drill holes to determine semiquantitatively the natural gamma radioactivity of geologic formations and the distribution of nuclear-explosion-produced radioisotopes.

From abstract: This report summarizes the porosity, density, and water content data on about 200 tuff specimens from the Tunnel Beds which compose the lower member of the Oak Spring Formation of Miocene (?) or younger age at the Ul2e tunnel, Rainier Mesa, Nevada Test Site.

The following report follows geological investigations made on the 410 Area of the Nevada Test Site.

From introduction: This report contains the preliminary results of the USGS investigations of the geology of the U12b.07 tunnel and shaft, and the U12b.09 tunnel at the Nevada Test Site.

From introduction: This report contains part of the geologic information obtained from investigations conducted by the USGS on behalf of the AEC to determine the geologic environment of the underground test sites at Nevada Test Site.

From introduction: This report is a summary of geologic information obtained by the USGS at Dolomite Hill, Nevada.

"This Progress report describes a part of a continuing geophysical program being conducted by the U.S. Geological Survey on behalf of the Albuquerque Operations Office, U.S. Atomic Energy Commission"

This is a photo-geologic map of the Skull Mountain Quadrangle at the Nevada Test Site.

This is a geological map of the Silent Butte quadrangle in Nye County, Nevada.

From introduction: This report details Vela Uniform program survey that determined the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel for comparison with similar post-shot geologic data and evaluated these data in terms of predicting the geologic effects of the planned explosion.

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.

From introduction: The geologic studies in the U12e.04 tunnel within the Nevada Test Site were conducted for the purpose of determining the structure and chemical and physical properties of the tuffs exposed in the tunnel.

From introduction: USGS is appraising the possibility, however slight, that the ground water beneath the Nevada Test Site, possibly contaminated by nuclear detonations, may carry radioactive fission products to places where they may constitute a public hazard.

This is a preliminary geologic map of a section of the Nevada Test Site.

The following report covers geological studies on the USGS and Rainier tunnel areas in the Nevada Test Site.
