This GEOTHERM sample file contains 1367 records for Nevada. The records contain data on location, sample description, analysis type, collection condition, flow rates, and the chemical and physical properties of the fluid. Stable and radioactive isotope data are occassionally available. (ACR)

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.

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

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.

Report describing the results of geochemical and stream sediment reconnaissance sampling in the Kingman Quadrangle, to look for uranium and trace elements, and to take other measurements.

Report describing the results of geochemical and stream sediment reconnaissance sampling in the Las Vegas Quadrangle, to look for uranium and trace elements, and to take other measurements.

From introduction: This report presents engineering details, history, well logs, and a brief geologic interpretation of the Carson Sink, Nevada, drilling program. A geologic report is in preparation and the geologic information contained herein is of a preliminary nature.

From introduction: The objective of this survey is to develop a geochemical data base for use by the private sector to locate regions of anomalous uranium content. Prior to wide area coverage, several pilot studies are being undertaken to develop and evaluate sampling and analytical techniques. The first of these studies was conducted in the Walker River Basin.

Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."

Abstract: "Wind observations collected at Yucca Flat since 1951 are analyzed for timewise variability. Variability functions of altitude, season, wind speed, and vector wind are described. Derived variability parameters are incorporated into calculations of fallout safety probability for NTS operations."

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: This report summarizes the work that was done at the wells and brings together the available data on depth to bottom, depth to water level, discharge rate, and draw-down for each well, together with coefficients of transmissibility determined in aquifer tests.

From introduction: The geologic studies in the U12e.04 tunnel within the Nevada Test Site were conducted for the purpose of determining the structure and chemical and physical properties of the tuffs exposed in the tunnel.
