The following report describes the high pressure and temperature homogeneous reactor experiment which has been started at Los Alamos, as well as the hazards and safety aspects for the experiments.

Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Permian and Pennsylvanian age south of Coyote, Mora County, New Mexico. Detailed mapping and sampling of these deposits indicate that they occur in carbonaceous zones in shales and arkosic sand-stones. Samples contain as much as 0.067 percent uranium. A yellow radioactive mineral found in the deposits was identified as metatyuyamunite. All of the samples were collected near the surface and are weathered. It is recommended that physical exploration be undertaken to determine the extent and grade of uranium-bearing zones at depth.

From introduction: The reconnaissance was made during the summer of 1951 by two field parties: (1) a reconnaissance in parts of Oklahoma, Texas, New Mexico, and Arizona by Russell Gibson, and (2) Geological Survey reconnaissance in parts of New Mexico,.Colorado, Utah, Idaho, and Wyoming (by the writers), the results of which are summarized in this report.

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.

Objectives: The purpose of this project was to study in detail the factors controlling the formation of fractures and the fracture pattern actually developed in an area transitional between Colorado Plateau and Basin and Range type structures.

From Operational Program: This final report includes a general geologic description of the area, including descriptions of the various geologic units and correlates the airborne data to the geologic units as provided by the geologic maps. Also included is a frequency distribution study of the data as a function of the geologic units encountered over the NTMS area including the tie line data.

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).

From abstract: The copper and uranium-vanadium deposits of the Coyote district, Mora County, N. Mex., are confined to the lower 2,000 feet of the Sangre de Cristo formation of Pennsylvanian and Permian age. A narrow belt of deposits in steeply dipping or overturned rocks extends for 7 miles along Coyote Creek south of Guadalupita. Earlier studies showed that the copper deposits contained uranium, but both the reserves and the uranium content of the copper-bearing shale are too low to permit the recovery of uranium. However, small, commercial grade uranium deposits have been discovered in sandstone.

This is a geological map of the uranium region of the Colorado Plateau.

A report about copper and uranium deposits of the Coyote district, Mora County, N. Mex., are confined to the lower 2,000 feet of the Sangre de Cristo formation of Pennsylvanian and Permian age.

Report discussing the investigation of possibly commercial amounts of thorium, niobium and rare earths which were found in veins of igneous rock areas in Laughlin Peak, New Mexico.

The following report is a synopsis of readily available information on the mineralogy, thickness and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas. It's part of a more extensive investigation of salt being carried out by the U.S. Geological Survey in connection with its Investigation of Geologic Processes project on behalf of the Division of Research, U.S. Atomic Energy Commission.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

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

Abstract: "This report indicates some of the methods employed at Los Alamos for the fabrication of refractory products."

From Purpose and Scope: "The Tularosa Quadrangle (2º), New Mexico (Fig. 1), was evaluated to identify geologic units and delineate specific areas that have characteristics favorable for occurrence of uranium deposits. All geologic environments to a depth of 1500 m were evaluated by means of surface investigations and examination of geophysical well logs."
