Geophysical logs for 12 holes drilled for the Oakville-Goliad Project in the Laredo-McAllen Quadrangles, Texas by the Bendix Field Engineering Corporation, Grand Junction, Colorado.

This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the 12 holes drilled for this project.

From summary: As the principal objective of this study is to identify the most useful geologic characteristics, referred to as recognition criteria, and develop a method for their systematic use in resource studies and exploration, the important geologic observations on the uranium deposits of South Texas are briefly summarized below.

First volume of a final report documenting the results of an airborne radiometric and magnetic survey in a portion of Alaska, including a description of the survey methods, calibration of the systems, data processing and displays, and interpretation methods.

Second volume of a final report documenting the results of an airborne radiometric and magnetic survey, including data displays and interpretation results for the Norton Bay quadrangle.

Average record data listings taken during aerial gamma-ray and magnetic surveys of the Norton Bay quadrangle in Alaska.

Single record data listings taken during aerial gamma-ray and magnetic surveys of the Norton Bay quadrangle in Alaska.

From purpose: The purpose of this study was to examine the Precambrian conglomerates of central Arizona in sufficient depth to determine whether they contain any obvious uranium concentrations and whether their geologic environment of deposition was permissive or prohibitive of conditions favoring uranium concentration.

Appendices containing supplementary data including, geologic unit codes, grain size classification, sample summary tables, results print-outs, and site descriptions to accompany a report on uranium potential in Arizona.

This report presents geophysical data taken from the Sonora Pass drilling project in Alpine and Tuolumne counties, 1979.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Texas portions of the Beeville (NH 14-12 quadrangle) and Bay City (NH 15-10 quadrangle) National Topographic Map segments including a description of the program and results.

Photomicrographs of 59 rock thin sections from shallow sandstone-type deposits in Eocene rocks mined from the Red Desert in south-central Wyoming (see pages 395-402 of report).

"This report consists of engineering details, statistics, individual borehole histories, and logistics for the 27 boreholes drilled in the project. Geophysical logs are included." (from Introduction)

From summary: The procedure has been to search for areas in which nonpedogenic calcrete or gypcrete may have developed and where additional study or exploration might be justified.

This report follows a rotary-wing high sensitivity radiometric and magnetic survey that was flown covering a portion of the Lakeview Oregon area.

From summary: Granitic and contact-metamorphic rocks of the Owens Valley area were sampled to determine their favorability for uranium. Uranium deposits associated with these rocks were examined to determine the mode of occurrence.

Supplementary data containing geologic, location, and radiometric maps of Owens Valley area, Inyo and Mono Counties, California, and Esmeralda and Mineral Counties, Nevada.

From synopsis: The discovery of the Rabbit Lake deposit, Saskatchewan, in 1968 and the East Alligator Rivers district, Northern Territory, Australia, in 1970 established the Lower-Middle Proterozoic veinlike-type deposits as one of the major types of uranium deposits. The term "veinlike" is used herein for this type of deposit in order to distinguish it from the classical magmatic-hydrothermal "vein" or "veintype" deposits. The veinlike deposits exhibit distinct geologic features and are now known to include the largest and the richest uranium deposits of the world. At present they account for between a quarter and a third of the Western World's proven uranium reserves.

From introduction: This report describes work done in the Durango National Topographic Map Series (NTMS) quadrangle, Colorado, by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

Final report analyzing aerial gamma ray and magnetic data in the Danville quadrangle, including a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.
