From summary: Site investigations were conducted at two locations, the sites of the DUGOUT and CHARLIE events, at the Nevada Test Site for the purpose of evaluating the dynamic in situ technique as a means of determining the boundaries of craters produced by explosive detonations.

This report describes the simplified methods used to obtain the magnetic property data required to interpret an aeromagnetic survey of 5,000 square miles in the general area of the Nevada Test Site.

From summary: The USGS (U.S. Geological Survey) and the USBM (U.S. Bureau of Mines) studied the mineral resource potential of 50,499 acres of the 61,137-acre Weepah Spring Wilderness Study Area (NV-040-246), Lincoln and Nye Counties, Nev., at the request of the BLM (U.S. Bureau of Land Management). In this report, the area studied is referred to as the "wilderness study area" or the "study area." Field studies of the area were conducted during summer 1984 by USBM geologists and during spring 1984 and fall 1985 by USGS geologists, geochemists, and geophysicists.

A complex pattern of active faults occurs in the southern Amargosa Desert, southern Nye, County, Nevada. These faults can be grouped into three main fault systems: (1) a NE-striking zone of faults that forms the southwest extension of the left-lateral Rock Valley fault zone, in the much larger Spotted Range-Mine Mountain structural zone, (2) a N-striking fault zone coinciding with a NNW-trending alignment of springs that is either a northward continuation of a fault along the west side of the Resting Spring Range or a N-striking branch fault of the Pahrump fault system, and (3) a NW-striking fault zone which is parallel to the Pahrump fault system, but is offset approximately 5 km with a left step in southern Ash Meadows. These three fault zones suggest extension is occurring in an E-W direction, which is compatible with the {approximately}N10W structural grain prevalent in the Death Valley extensional region to the west.

The following report describes the computer technique for tracing seismic rays in two-dimensional geological models in the state during the time this report was written, and presents some preliminary results.

Report concerning the protection offered against radioactive fallout offered by two types of structures at the Nevada Test Site. Differences between above ground and underground structures are measured and compared to data taken from actual fallout conditions.

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.

Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data."

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.

This report summarizes the environmental surveillance activities conducted by Sandia National Laboratories, the US Environmental Protection Agency, and Reynolds Electrical and Engineering Company for the Tonopah Test Range operated by Sandia National Laboratories. Sandia National Laboratories` responsibility for environmental monitoring results extend to those activities performed by Sandia National Laboratories or under its direction. Results from other environmental monitoring activities are included to provide a measure of completeness in reporting. Other environmental compliance programs such as the National Environmental Policy Act of 1969, environmental permits, and environmental restoration and waste management programs are also included in this report, prepared for the US Department of Energy in compliance with DOE Order 5400.1.

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