Discussing a uranium reconnaissance program undertaken to evaluate formations that were producing uranium and vanadium ore in the Sanastee area.

Abstract: Reconnaissance for uranium in coal and black shale in New Mexico during 1952 was largely an extension of work initiated during the 1951 field season. No uranium deposits of economic interest were found, although minor amounts of uranium were noted at several localities.

From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

Abstract: Dark shale and arkosic sandstone south of Guadalupita, Mora County, New Mexico, contain as much as 4 percent copper and 0. 01 percent uranium on the basis of a few samples recently analyzed. The deposits occur primarily in the dark shale which is about 5 feet thick and dips about 900. Potential reserves of this material are very large. Prospecting and further geologic work will be necessary, however, to evaluate possibilities of these large tonnages. If the deposits can be mined for their copper content, the uranium might be recovered as a byproduct. Detailed mapping and possibly some trenching will be undertaken by the Geological Survey in order further to evaluate the deposits.

From abstract: Coal and carbonaceous shale of the Dakota formation of Cretaceous age were examined for radioactivity in the Colorado Plateau of southwestern Colorado and northwestern New Mexico during the summer of 1953.

Abstract: "A description of the instrumentation for neutron flux measurement from Kiwi-A at NTS is given as some discussion of start-up considerations, detector design, system response adjustments, and power calibration of the reactor at some low level of power."

The following document provides a mineralogical and geological map of the Colorado Plateau providing deposits and groups of deposits that have been found to produce 1,000 tons or more of uranium-vanadium within December 31, 1953.

Report discussing geophysical observations in parts of the Grants district of McKinley County, New Mexico. This study had the "dual objective of investigating the unusual occurrence of negative aeromagnetic anomalies in close association with airborne radioactivity anomalies, and of investigating other geophysical methods which might assist directly or indirectly in the search for uranium ores in the Grants district."

Abstract: Ten days were spent during June 1955, examining the sedimentary rocks along the San Juan and Colorado Rivers between Mexican Hat, Utah, and Lee's Ferry, Arizona. The most favorable area for uranium deposits occurs in the Shinarump member of the Chinle formation between Clay Hills Crossing and Spencer Camp along the San Juan River. Mineralization is spotty and deposits are small and almost all below ore-grade. Only one small mine, the Whirlwind, is currently producing ore. Gray-green alteration of the underlying Moenkopi is moderately developed in the vicinity of the Whirlwind mine; elsewhere alteration is weakly developed.

Abstract: This document is a survey analysis of soil samples from Los Alamos, Pueblo, Bayo, and Mortandad canyons to determine the presence and activities of radioactive contaminants. Also included are the results of analyses of a few samples of grass and of surface water. This survey covers the period from spring 1953 to spring 1955.

Summarizing and presenting the interpretations and conclusions based on the drilling through Phase II of the program.

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

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 introduction: The primary object of this work was to aid prospectors and mining men in finding and exploiting new deposits of uranium-bearing ores in the Colorado Plateau region, particularly of those in the Shinarump and Moss Black members of the Chinle formation.

The US Atomic Energy Commission conducted a drilling program in McKinley County, New Mexico, from August 19, 1953, through April 19, 1954, to explore the Jurassic Todilto limestone for uranium occurrences on the eastern, northeastern, northern and northwestern sides of Haystack Butte
