The following report summarizes the results of a brief geological examination made by the Geological Survey of the small uranium deposit in the Majuba Hill mine, Pershing County, Nevada.

From abstract: Uranium is associated with copper and tin ores in the Majuba Hill area, Antelope mining district, in the central part of the Antelope Range, Pershing County, Nev. About 23, 000 tons of copper and 200 tons of tin ore, a small quantity of lead-silver ore, and some arsenic-silver ore have been produced from the Majuba Hill mine, the Last Chance mine, and a mine in sec. 34, T. 33 N., R. 31 E.

The following report is a compilation of lithologic logs, drillers logs, drilling records, and hydrologic data on 18 wells and test holes that were drilled in the Nevada Test Site and surrounding areas prior to 1960.

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.

Abstract: Geophysical logs, a summary of contract costs, detailed descriptions of drilling, casing, cementing, and hydraulic testing operations, X-ray mineralogical analyses, physical property analyses, and a detailed lithologic log are presented in the report.

Introduction: The chemical character of ground water depends to a large degree upon the character of the rock formations through which the water moves. The composition of the water is the result of several solutional and decompositional processes.

Abstract: Ground-water test well 2 was drilled to a depth of 3,422 feet with rotary and cable tool drilling equipment.

Introduction: The United States Atomic Energy Commission is considering the establishment of a townsite in the vicinity of Mercury, Nevada, to facilitate operations at the Nuclear Rocket Development Station on the Nevada Test Site.

From introduction: This report summarizes the available hydrologic information for a part of Nevada surrounding the Nevada Test Site. It emphasizes the possibility that ground water may move from one basin to another, whereas the usual concept heretofore has been that the ground water of the region generally occurs in basins that are closed or nearly closed.

"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 results presented in this preliminary report are principally concerned with the ground motion caused by seven underground nuclear explosions (table 1) in the bedded tuff of the Oak Spring formation in Area 12. Ground motions were recorded at stations as close as 5 kilometers and as far as 300 kilometers from the explosions (fig 1 and table 2). The results for the Bianca and especially the Evans explosion are meager because the first was accompanied by a Test Site-wide moznentary power failure and because the yield of the second was so far below the anticipated yield that uncertain results were obtained. Ground motions caused by most of the air explosions in Operations Plumbbob and Hadtack - Phase 2 were recorded and have been partly analyzed. Results are presented in this report only where they relate significantly to analysis of the underground explosions. The effects of most of the small underground explosions in Area 3 (center of Yucca Flat) that had significant yields were also recorded. The results have not yet been interpreted.

Introduction: The U.S. Geological Survey 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.

Introduction: Geologic studies by the U.S. Geological Survey in support of the U.S. Air Force's Project Pluto in Area 401 of the Nevada Test Site were made on behalf of the U.S. Atomic energy Commission.
