The results of a high-sensitivity, aerial gamma-ray spectrometer and magnetometer survey of the Holbrook two degree quadrangle, Arizona are presented. Instrumentation and methods are described in Volume 1 of this final report. The work was done by Carson Helicopters, Inc., and Carson Helicopters was assisted in the interpretation by International Exploration, Inc. The work was performed for the US Department of Energy - National Uranium Resource Evaluation (NURE) program. Analysis of this radiometric data yielded 260 statistically significant eU anomalies. Of this number, forty-four were considered to be of sufficient strength to warrant further investigation. These preferred anomalies are separated into groups having some geologic aspect in common.

From abstract: This drilling project in northwestern Arizona consisted of 18 holes drilled to depths ranging from 1,341 to 5,491 feet (409 to 1,673 meters). The holes were sited to determine the lateral extent of the uranium-bearing, paludal/lacustrine strata of the Anderson Mine in Date Creek basin and to obtain additional data to improve the resource estimates for the Date Creek and Big Sandy basins.

From abstract: As part of the Department of Energy (DOE) National Uranium Resource Evaluation Program, a rotary-wing high sensitivity radiometric and magnetic survey was flown covering portions of the State of New Mexico, Arizona and Texas. The survey encompassed six 1:250,000 scale quadrangles, Holbrook, El Paso, Las Cruces, Carlsbad, Fort Sumner and Roswell.

Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the nine holes drilled in the Great Divide Basin 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.

Supplementary data containing geophysical logs to accompany a geologic report on drilling in the Western Prescott and Williams Quadrangles.

Supplementary data containing geophysical logs for drilling hole BRD-18 to accompany an engineering report on the Great Divide Drilling Project in Sweetwater County, Wyoming.

Logs describing lithologic characteristics of samples collected from the project area described using a binocular microscope or hand lens and recorded on standard Bendix Field Engineering Corporation (BFEC) logging forms.

The purpose of this report is to summarize the information obtained by the project, to make geologic interpretations of the information, and to transmit the information and interpretations of the information to the U.S. Department of Energy and the Geology Division of Bendix Field Engineering Corporation, Grand Junction Colorado.

Photomicrographs of core samples submitted for petrographic analysis from Moffat and Routt Counties in northwest Colorado collected for the Sand Wash Basin Drilling Project, which identified areas in the region favorable for uranium occurrences.

This folio of maps is designed to represent an atlas of the geophysical data publicly available in the Van Horn, Pecos, Marfa,Fort Stockton, Presidio, and Emory Peak Quadrangles and represents a major file of basic data which has already been the object of much industrial interest.
