This following report discusses the studies and findings of the East Chaco Canyon drilling project of northwestern New Mexico. These studies took place between July and November of 1978.

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: This volume contains information and survey results pertaining specifically to the Saint Johns NTMS 1:250,000 scale Quadrangle, Arizona and New Mexico, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

This report contains aerial radiometric and magnetic survey data for Tularosa National Topographic Map of New Mexico.

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.

As part of the LASL portion of the US EROA NURE program, water samples from 534 locations and sediment samples from 2936 locations were taken over a 7770 square kilometers area of the Estancia Valley in 1975 and analyzed for uranium.

This report contains aerial gamma-ray and magnetic quadrangle maps of portions of New Mexico, Arizona and Texas.

From preface: The report which follows is the second phase of a DOE contract designed to address various aspects of the genesis of the uranium deposits of the Grants mineral.belt. Many of the problems outlined in Phase 1 of this study (Brookins, 1976a) have been answered, others have been raised.

This is a report on aerial radiometric and magnetic reconnaissance survey of portions of Arizona and New Mexico in the Tucson Quadrangle.

This is a report on aerial radiometric and magnetic reconnaissance survey of portions of Arizona and New Mexico in the Silver City Quadrangle.

This is the second part of a report of a uranium hydrogeochemical and stream sediment pilot survey of areas of New Mexico.

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).

From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

This is a report on aerial gamma ray and magnetic survey, Raton Basin Project, in the Albuquerque Quadrangle, New Mexico.
