"This document provides a detailed description of Data Reports of the western quadrangles that have been prepared by Savannah River Laboratory (SRL) personnel for the National Uranium Resource Evaluation (NURE) program. The Guide includes descriptions of (1) sample collection and field measurements: (2) format, abbreviations, and codes used in data tables: (3) graphical presentation and maps: and (4) quality assurance programs for sample collection and analysis." (Abstract)

Symbol plot maps, histograms, and frequency distribution plots for U, Th, Hf, Ce, Fe, Mn, Sc, Na, Ti, and V elements; U/Th and U/Hf elemental ratios; and scintillometer readings for the S1 fine (<149 mu/m) sediment samples.

A report regarding a mineral evaluation of part of the Gold Butte district, in Clark County, Nevada

From introduction: This report includes a brief description of the stratigraphy and structure, and data on petrology, mineralogy, and chemical and physical properties of the rocks that are exposed in the U12b.01 tunnel of the U12b (Rainier) tunnel system.

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

From introduction: The geologic studies in the Ul2e.03a and Ul2e.03b tunnels were conducted as part of the Geological Survey's investigations for the Vela Uniform program, Project Shade, and were completed for the purpose of 1) determining the preshot lithologic, structural, and chemical and physical properties of the tuffs exposed in the tunnels for comparison wits postshot geologic data, and 2) evaluating these data in order to predict the geologic effects of the planned nuclear explosion at tie end of the tunnels.

From introduction: The geologic studies in the U12b.08 tunnel were conducted by the U. S. Geological Survey on behalf of the U. S. Atomic Energy Commission for the purpose of determining the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel. These data will be used in evaluating the geologic effects of the explosion by comparison with similar post-shot geologic data.

From Introduction: "The Las Vegas Quadrangle, Nevada, Arizona, and California (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

Appendix containing data on uranium availability in the Las Vegas Quadrangle to accompany a report on U.S. uranium resources in Nevada, Arizona, and California.

Supplementary data containing geophysical logs to accompany an engineering report on the McDermitt Caladera Drilling Project in Nevada and Oregon.

Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the eleven holes drilled in the McDermitt caldera project during the 1981 drilling program. General information is presented regarding specific problems, including weather and logistics. A separate geologic report is being prepared and will be available through the Bendix Field Engineering Corporation Technical Library in the near future.
