The following report is the second volume discussing airborne radiometric and magnetic data from New Mexico within the Santa Fe quadrangle. This report provides detailed data descriptions from the study.

Three formations in the Tertiary of the San Juan Basin were investigated for their uranium favorability. They are the Ojo Alamo Sandstone, the Nacimiento Formation, and the San Jose Formation. The study comprised a literature survey and a basin analysis, which consisted of subsurface lithofacies, stratigraphic, and radiometric mapping. Field work in preparation for the subsurface analysis consisted of examination of outcrop and measured sections, surface radiometric traverses, and checking of reported surface radioactive anomalies.

This report presents the results of a preliminary study of the uranium favorability of the Sangre de Cristo Formation (Pennsylvanian-Permian) in the Las Vegas basin, northeastern New Mexico. Because known uranium deposits are confined mainly to the Sangre de Cristo, the following discussions are limited to this formation. The study focuses on sedimentologic and stratigraphic characteristics relevant to uranium deposition. The investigation was conducted by Bendix Field Engineering Corporation (BFEC) on behalf of the U.S. Energy Research and Development Administration (ERDA).

The following report provides data maps and charts for flight line mean-values, statistical summaries, histograms, and stacked profiles for the Dalhart quadrangle.

Flight-line averaged data taken during aerial gamma-ray and magnetic surveys, documenting mean values of eU, eTh, K, eU/eTh, eU/K, and eTh/K in geologic units for each flight line of the Dalhart quadrangle in New Mexico, Oklahoma, and Texas.

Statistical summary tables of data taken during aerial gamma-ray and magnetic surveys, listing distribution types, statistical parameters, and number of samples of eU, eTh, K, eU/eTh, eU/K, and eTh/K for the Dalhart quadrangle in New Mexico, Oklahoma, and Texas.

Averaged record (statistical analysis) data listings taken during aerial gamma-ray and magnetic surveys of the Dalhart quadrangle in New Mexico, Oklahoma, and Texas.

Single record (reduced data) listings taken during aerial gamma-ray and magnetic surveys of the Dalhart quadrangle in New Mexico, Oklahoma, and Texas.

A report regarding a probabilistic endowment appraisal system based upon the formalization of geologic decisions. Prepared for the U.S Department of Energy.
