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.

This report summarizes the geological analyses of one of the preliminary cross sections from the Pahute Mesa in the Nevada Test Site, particularly the uppermost Precambrian-Paleozoic strata.

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.

This report summarizes results on surveys taken by the U.S. Geological Survey made to determine the seismic velocity, electrical resistivity, and preliminary geology of rock in the U12n.03 tunnel, Nevada Test Site.

This report summarizes the results of the U.S. Geological Survey geophysical and geological studies of the rock in the U16a.04 tunnel in the Nevada Test Site.

The following report summarizes the geological and geophysical studies made on the rocks of the Midi Mist site in the Area-12 tunnel complex of the Nevada Test Site. The data was needed to determine whether the rock met the technical criteria of the nuclear experiment.

The following report summarizes the geophysical studies of the rocks made in the U12e.10 tunnel of the Nevada Test Site.

This report was formed after the study of the Nevada Test Site to examine parts of the thick miogeosynclinical section of the Paleozoic rocks and post-Paleozoic structural features for the sole purpose of determining the walking stops for future field trips to the test site.

This report summarizes the stratigraphy, lithology, and physical properties studied in the UE12p#1 exploratory diamond drill hole at the Nevada Test Site.

Abstract: "Geodimeter surveys were made on four traverses near the east scarp of Rainier Mesa between October 27, 1967 and April 26, 1968. These measurements were made in order to determine if an changes in distance between survey stations had resulted from downslope creep of the rocks behind the scarp, or if any displacements had resulted from nuclear explosions beneath the mesa and in adjacent areas. A persistent small but possibly significant, slopeward displacement was measured along one traverse and may represent detachment of a large block; monitoring for an additional period of time is recommended."

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"

From introduction: The papers comprising the various parts of this report contain the preliminary results of the U. S. Geological Survey investigations in the Ul2e.05 tunnel at the Atomic Energy Commission's Nevada Test Site, Nye County, Nevada (fig. 1). Reports on electrical resistivity, natural radioactivity, and heat required to raise the rocks to 100C will be issued later. A preliminary report on the geologic effects of the Blanca event is being prepared.
