Electrodeposition of Aluminum on Uranium
Abstract: "Aluminum electroplating was studied in a search for new methods of cladding uranium fuel elements. Uranium electroclad with 12 mils of aluminum over a 0.5-mil (or nickel plus copper) electroplate resisted corrosion for more than 100 hr in boiling water. This quality of protection was effected by hot pressing the electroclad uranium with 5.1 tons per sq in. for 5 min at 950 F. The electroclad uranium with hot-pressed samples paralleled those of later experiments with hot-pressed wrought aluminum claddings on uranium. In both cases, the uranium was electroplated with thin (0.5 mil) layers of metals to prevent aluminum-uranium diffusion, to aid bonding, and to assist in corrosion protection. This aluminum electroplating study helped to define the importance of the intermediate coating between the aluminum and the uranium, the effect of good bonds between the various layers, and the effects of hot pressing in protecting uranium with an aluminum cladding."

Notes on Evaporation of Target Materials
Abstract: "The general utility of vacuum evaporated films is discussed. The characteristics that makes this technique most useful are the uniformity of the films, the easy control of their thickness over a large range, and the adaptability of the system to different metals and compounds. The design of a vacuum evaporator should provide adequate pumping speed, cooling of components, filament heater supply, and general flexibility and adaptability of the components to different materials. The design of filaments or boats and the evaporation of Al, Ag, Au, Li, Na, UCl4, ThF4, Be, SiO, Nal (Tl), U, and UO2 are considered. Special attention is given to the problem of obtaining uniform layers of UO2 on a large, flat target relatively close to the source."

Tectonic Map of Eastern Montana Showing the Distribution of Uranium Deposits
From introduction: A tectonic map for the northern part of the Cordilleran Foreland was compiled to aid in establishing the geologic setting of uranium deposits within the region, and to determine what relationships, if any, exist between the distribution of uranium deposits and localities, and the regional tectonic pattern (Osterwald, 1955). The relationships might suggest new areas favorable for the discovery of uranium deposits in the Cordilleran Foreland as well as in other areas with similar tectonic history. The map will show the distribution of crest lines and troughs of folds, faults, uranium deposits and localities, and areas of volcanic activity. Outcrop areas of Precambrian and post-Eocene rocks are shown to designate the relative age of structures. Where possible the Precambrian rocks are subdivided into structural types, so that their influence on younger deformations may be inferred. The map of eastern Montana is one of a series being prepared before the final map is assembled (fig. 1.).

Geologic Features of Areas of Abnormal Radioactivity South of Ocala, Marion County, Florida
From abstract: Areas of abnormal radioactivity south of Ocala, Marion County, Fla., discovered in 1953 by aerial survey, were investigated by surface examination and by 10 power auger drill holes. Interbedded clay, clayey sand, and uraniferous phosphorite occur in the areas of anomalous radioactivity. Miocene fossils occur at three localities in these beds which are evidently outliers of Miocene sediments on the Ocala limestone of Eocene age. The preserved outliers are southwest of the main belt of Miocene sediments. The principal uraniferous rocks are clayey, sandy, pellet phosphorite that occurs in beds a few feet thick, and very porous, phosphatic sand rock which makes abundant float at many places. Apatite forms the phosphate pellets in the unweathered phosphorite. The very porous, phosphatic sand rock is the highly leached residuum of the pellet phosphorite and is composed mainly of quartz, kaolinite, wavellite, and crandallite ( pseudowavellite2). It closely resembles the aluminum phosphate rock of the "leached zone" of the Bone Valley formation in the land-pebble phosphate district.

Geophysical Investigations on the Gramlich Group, Paradox District, Montrose County, Colorado
From abstract: The U. S. Geological Survey made a geophysical investigation on the Gramlich group, Paradox district, Montrose County, Colo., during the period May 26 to July 11, 1952.. Electrical resistivity and self-potential surveys were made to determine the thickness of the upper Salt Wash sandstone and to test electrical prospecting methods in an area of shallow overburden. The investigations were made in conjunction with a diamond-drilling program.

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana
Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the Comet and Gray Eagle dumps, it is recommended that a minimum of four diamond drill holes totaling 3, 000 feet be drilled by AEC between the two mines to intersect the shear zone 300 to 500 feet below the surface. This drilling should be made contingent upon the results of the Gray Eagle exploration.
