An index and geological map of Nevada showing the Yucca Flat quadrangle.

From abstract and summary: Project Stagecoach consisted of the detonation of three 40,000-pound charges. Blocks of cast TNT were stacked to resemble a sphere and, the whole center-detonated.

From introduction: "This report presents physical property data of volcanic rocks underlying Rainier Mesa and vicinity in the northwest corner of the Yucca Flat area, Nevada Test Site."

Report containing information regarding the airborne radiometric equipment intercalibration exercises undertaken by four government agencies and one private companies.

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 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.

From introduction: The gravity survey of the Nevada Test Site and contiguous areas of southern Nevada and southeastern California has been made by the U.S. Geological Survey on behalf of the U.S. Atomic Energy Commission. The objective of this study is to delineate and interpret gravity anomalies and regional trends so that the configuration and depth of the buried erosional surface of the Paleozoic rocks may be determined.

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 introduction: "This report was compiled to bring together the well data collected by the U.S. Geological Survey since 1960. This compilation includes data on 63 wells and test holes which were drilled since the Moore reports were prepared, or which were deepened or otherwise modified since 1960."

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

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.

From purpose and scope: The purpose of this report is to present all the previously collected hydrogeologic, geophysical, and hydrochemical data on well J-13, and to reanalyze these data, using newly developed methods of analysis.

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.

The following report summarizes the hydrologic data collected during the nuclear detonation, the Bilby event, that took place in the U3cn emplacement hole.

From abstract: This report includes results of studies of crater dimension, throwout material distribution, ground motion, dust cloud growth, and long-range air blast.

Abstract: "ground-water test well A was drilled to a depth of 1,870 feet with rotary and cable-tool equipment. Only alluvial materials were penetrated. These were saturated below 1,605 feet. Pumping and bailing tests indicate that the minimum transmissibility of the alluvium is about 800 gallons per day per foot. The specific capacity was 1.9 gallons per minute per foot of drawdown after 1 hours of pumping at rates of both 41 and 60 gallons per minute. A suite of geophysical logs, a summary of contract costs, and a detailed description of drilling equipment and casing record are presented."

From contributions of astrogeology: The principal goal of research in astrogeology is the solution of several cardinal problems of geology...The present volume is the first of a series of professional papers that will describe major results of research in astrogeology.
