From introduction: This report describes the program of research on mineralogy and petrography of certain uraniferous vein deposits in the Boulder batholith of western Montana.

Abstract: Uranium associated with peat humus was discovered in a boggy meadow in the Sierra Nevada of Kern County, California, in the fall of 1955.

Introduction: Atomic Energy Facts is designed to serve as an introduction to nuclear operations in the United States and as a handbook of related information for the use of industrial firms and other active or interested in atomic energy.

Purpose: A reconnaissance was conducted during parts of August and September, 1956, of an area about two miles square in the southern Carrizo Mountains where the Permian Cutler formation, including its DeChelly member, and the Triassic Shinarump member of the Chinle formation, are exposed. The purpose was to appraise the uranium potential of the area and to determine the cause of bleaching in the DeChelly. Extensive uranium mineralization in the Salt Wash member of the Morrison formation around the Carrizo Mountaind suggested that the Shinarump, a good producer in other areas on the Colorado Plateau, might be mineralized here as well. Bleaching, as shown in the DeChelly; has proven such a useful guide to uranium at other localities as to merit investigation here.

Abstract: Mine mapping of the tyuyamunite-type deposits In the Salt Wash member of the Jurassic Morrison formation of the Lukachukai Mountains, Apache County, Arizona revealed recognizable spatial relationships between ore mineralization and: fractured areas, sedimentary features, and interstitial carbonate.

From introduction: A subsurface exploration program was undertaken to investigate the concentration of uranium and vanadium in or near the base of the Shinarump member of the Chinle formation in the Flatirons locality, and to develop criteria whereby adjacent unexplored areas could be evaluated as to potential production capacity from study of geological and mineralogical features at the host rook outcrop. An earlier study of the area by C. G. Evensen of the U. S. Atomic Energy Commission had shown that geological conditions favorable to the accumulation of commercial uranium deposits were present in the Flatirons area.

Abstract: Napier Drilling Company of Dallas, Texas drilled 53,998.0 feet for exploration purposes, under Contract No. AT(05-1)-256. This footage was drilled in 508 holes during the period from June 21, 1954 through May 13, 1955.

Subject: This report presents an investigation of a reportedly large low-grade ore body in the vicinity of Cameron, Arizona.

From purpose and scope: This report is designed to summarize the available information on the geology and ore reserves of the uranium deposits. Detailed geological work has been confined largely to those areas which contain the more promising uranium occurrences with at least 80 percent of such work being concentrated in the Sierra Ancha district.

Abstract: The discovery and exploration of primary uranium mineralization in the Sierra Anchas of east-central Arizona made possible an analysis of the structural ore controls.

From introduction: The primary purpose of this report is to record the bases chosen in setting the Commission's policy on processing charges to assure that individual charges are on a consistent basis in conformance with the policy. Secondly, it may aid reactor operators in estimating the AEC processing charges for a variety of fuels and reactor conditions. It may also be of interest to potential chemical processors by showing the approach followed in developing these charges.

Abstract: On July 16, 1953, a diamond core-drilling program was begun in the Pumpkin Buttes area to secure geologic information.

Abstract: A program of airborne radiometric reconnaissance for uranium was conducted in eastern Fremont and western Natrona Counties, in central Wyoming, during the summer and fall of 1954, by the U.S. Atomic Energy Commission.

From abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.

Supplementary data containing an index map of uranium occurrences in Gila County to accompany a report on U.S. uranium resources in Gila County, Arizona.

From introduction: The primary aim of this study is to present as complete a geologic picture as possible, of the Chattanooga shale in its outcrop area of the Eastern Highland Rim and the Northern Highland Rim of Tennessee and adjacent Kentucky. Special emphasis has been placed upon the stratigraphic relationships and their implications upon the age and manner of origin of the sediments and upon the origin, source, and distribution of uranium in the shale.

Abstract: Weak uranium mineralization is widespread throughout the Uinta Basin of northeastern Utah and northwestern Colorado, in rocks ranging in age from Permian to Eocene. No commercial ore bodies are known, although formations there have characteristics elsewhere considered favorable for ore deposition.

The following report studies uranium ore deposits discovered in the Browns Park Formation, south-central Wyoming and northwest Colorado.

"The principal uranium deposits in southcentral Wyoming and north-western Colorado are located in or at the margins of broad Tertiary basins. Interesting and possibly commercially significant occurrences are found in other Tertiary and older rocks at widely separated locations within this region. The six maps accompanying this report give the location, name, and ownership of the mines and occurrences from which samples assaying greater than 0.10% U3O8 have been collected. Claim names, location, and ownership are also given for occurrences outside the map areas."

Abstract: "Data on the isotopic degradation of heavy water used to deuterize deionizer beds at Savannah River Plant are presented. Also, the extent to which light hydrogen, chemically bound to aluminum surfaces may degrade heavy water is estimated."

Abstract: "A series of ternary additions of niobium, platinum, and molybdenum, of the order of 1.0 w/o and less, have been made to binary uranium - 0.5 w/o titanium, an alloy of some promise in the 7-heat-treated, water-quenched condition. Jominy bars of nine such alloys were tested, microstructurally examined, and hardness profiles obtained over their length. This paper deals with observations made for correlation of transformation behavior, microstructure, and hardness profiles over the spectrum of cooling rates experienced, directed toward the end of determining the effect of ternary additions in improving the properties of uranium."

This report follows studies that were made the quasi-stable pinch produced by a relatively long duration low voltage capacitor discharge (5ma, 5kv) in a 600 cm long, 15 cm diameter metal tube.

Abstract: "The problem of evaluating the method of sampling used on a particular uranium ore or concentrate is considered. It is pointed out that the purpose of this evaluation is to obtain data on possible biases of the sampling method, the way the sample is prepared for analysis, and the analysis itself. In addition, it is pointed out that some estimate of precision, either overall or individually, for each step is required. Examples of the use of the analysis of variance approach to these problems are given. Finally, some remarks are included on sampling problems associated with other materials used by the Food Materials Production Center."
