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.

From introduction: This report summarizes the information obtained during preparation of the lithologic log of the core and presents results of chemical analyses of marble samples collected from surface near the drill hole. The report was prepared by the U.S. Geological Survey on behalf of the Albuquerque Operations Office, U.S. Atomic Energy Commission.

From introduction: The "Granite" exploration hole was core drilled to determine the character of the igneous rocks from the surface to a depth of 1,200 feet and the degree of structural anisotropism of the rock within 200 feet of a point 950 feet below the surface. This report summarizes the data on the structure, chemistry, petrology and alteration of the rocks exposed at the surface in the immediate vicinity of the drill site and in the core.

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

From introduction: This report details the results of instrument recordings of a nuclear explosion where ground zero was near the top of Rainier Mesa.

From scope of report: "This report summarizes an interpretation of the geology of Yucca Valley to depths of about 2,300 feet below the surface, the characteristic features of ground water in Yucca and Frenchman Valleys, and the seismic, gravity, and magnetic data for these valleys."

"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"

A report regarding geological survey investigations in the U12b.03 and U12b.04 Tunnels, located at a Nevada test site.

"This report summarizes an interpretation of the geology of Yucca Valley to depths of about 2,300 feet below the surface, the characteristic features of groundwater in Yucca and Frenchman Valleys."
