From purpose and scope: The objective of this study was to delineate areas of maximum uranium favorability in Tertiary sediments that underlie part of the South Texas Coastal Plain.

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.

This is a set of 62 plates that accompany a report on uranium favorability in rocks of the south Texas coastal plain.

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.

From introduction: This report presents the results of a preliminary study of the uranium favorability of lower and middle Eocene rocks in the Wilcox and Claiborne Groups in the Texas Gulf Coastal Plain. The project began October 1, 1976, and was completed March 1, 1977, by personnel of Bendix Field Engineering Corporation (BFEC) under the auspices of the U.S. Energy Research and Development Administration (ERDA).

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Texas portions of the Corpus Christi (NG 14-2 quadrangle) and Laredo (NG 14-3 quadrangle) National Topographic Map segments including a description of the program and results.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Brownsville and McAllen National Topographic Map segments including a description of the program and results.

First volume of a report describing the program and results of investigations on the Seguin NTMS quadrangle.

From objectives: This report demonstrates the concept of hydrogeochemical sampling to be used in the 12-state region for which UCC-ND has the responsibility if surveying as part of the NURE. The results of a geochemical survey at two sample spacings in the Crystal City Quadrangle in south Texas are presented.

From objectives: This report describes the physical geology of the Catahoula Formation-its genetic stratigraphy, structure, mineralogical composition, and post-depositional history and discusses the known distribution of uranium within the context of these geological parameters. Emphasis is on definition of primary physical and historical factors affecting the mobilization, transport, and concentration of uranium in the Catahoula Formation.

STAARS is a new series which is being published to disseminate information concerning statistical procedures for interpreting aerial radiometric data.

This report presents field and laboratory results of 508 groundwater samples and 96 stream sediment samples for a reconnaissance geochemical survey of the Houston quadrangle, Texas.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Houston National Topographic Map segment (NH 15-7 quadrangle) including a description of the program and results.

A report discussing groundwaters from aquifers in two different sandstone-type uranium mining districts in Texas and Wyoming that were collected and chemically analyzed.

From abstract: A Principal Components Analysis (PCA) program has been written to aid in the interpretation of multivariate aerial radiometric data collected by the U.S. Department of Energy (DOE) under the National Uranium Resource Evaluation (NURE) program. The variations exhibited by these data have been reduced and classified into a number of linear combinations by using the PCA program. The PCA program then generates histograms and outlier maps of the individual variates. Black and white plots can be made on a Calcomp plotter by the application of follow-up programs. All programs referred to in this guide were written for a DEC-10. From this analysis a geologist may begin to interpret the data structure. Insight into geological processes underlying the data may be obtained.

This report explains the development of data enhancement and display techniques for geochemical data in the Hydrochemical and Stream Sediment Reconnaissance (HSSR) surveys taken in the Winston-Salem quadrangle in North Carolina, Virginia, and Tennessee.

This report is the first volume of a two-part set documenting the results of the analyses of the airborne gamma radiation and total magnetic field survey that was flown for the Austin National Topographic Map NH14-6.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.
