Niobium Phase Diagrams : Manuscript Report on Niobium-Oxygen System
Abstract: "The niobium-oxygen equilibrium has been determined by metallographic examination of arc-cast alloys made of electron-gun-refined niobium metal and special purity niobium pentoxide. Two intermediate oxides, NbO and NbO2, melt without decomposition at 1945 C and 1915 C, respectively. Eutectic reactions exist between niobium and NbO and 1915 C and between NbO and NbO2 at 1810 C. Experimental supports a peritectic reaction between NbO2 and Nb2O5 1510 C. The maximum solid solubility of oxygen in niobium metal is 0.72 weight per cent."

Tectonic Map of Western South Dakota Showing the Distribution of Uranium Deposits
From introduction: A tectonic map of most of the Cordilleran Foreland (fig. 2) is being compiled as an aid to study the geologic setting of uranium deposits within the region, and to determine what relationships may exist between the distribution of uranium deposits and the regional tectonic pattern (Osterwald, 1955). The map will show the distribution of faults, uranium deposits, areas of volcanic activity, and crestlines and troughs of folds.

Tectonic Map of Wyoming, East of the Overthrust Belt, Showing the Distribution of Uranium Deposits
From introduction: The compilation of the tectonic map of Wyoming east of the overthrust belt (area 6, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps and from unpublished data supplied by Government agencies, private companies, and independent geologists. The tectonic map of Wyoming east of the overthrust belt is only a progress report; any suggestions for corrections or additions will be appreciated.

Salt at Shallow Depths in the Coastal Plain of Texas and Louisiana
From introduction: Salt occurs at depths less than 500 feet in six salt domes in Texas and Louisiana. Underground mining operations are being carried out in each of these domes. The following notes have been prepared in an effort to furnish data regarding chemical composition and structure of the rock salt in the shallow deposits.

Eastern and Central Montana as a Possible Source Area of Uranium
From abstract: Geologic settings are recognized in central and eastern Montana and in a few places in southwestern Montana that elsewhere are similar to the settings for the occurrence of uranium deposits. Several specific areas in Montana seem favorable for the occurrence of uranium.

Tectonic Map of Northern Colorado and Northeastern Utah, Showing the Distribution of Uranium Deposits
From introduction: The compilation of the tectonic map of northern Colorado and northeastern Utah (area h, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps, and from unpublished data supplied by government agencies, private companies, and independent geologists. The various structures of the Foreland can be divided into three large classes to show the relation of uranium deposits to the structural pattern.

Radioactive Manganese Occurrences in the Lower Rio Itapicurú Valley, Bahia, Brazil
From abstract: Radioactive manganese deposits have been found in two swamps and at one locality on the northeast bank of the Rio Itapicuru near Mosquete, municipio of Itapicuru, State of Bahia, Brazil. The occurrences are related to warm springs and consist of surficial manganiferous sinter and of sandstone impregnated with manganese.

The Uranium Occurrences in the Martha E Prospect, Lawson-Dumont District, Clear Creek County, Colorado
From introduction: The Martha E prospect, in Spring Gulch about three and one-half miles southwest of Idaho Springs, Colo. (fig. 1), is on a claim, originally called the Daisy Freese, which was first prospected by the Stanley Mines. The occurrence of radioactive minerals in the adit was called to the attention of the U. S. Geological Survey in 1950 by the owners of the claim. The Survey's Trace Elements Section Washington Laboratory identified metatorbernite, autunite, and sooty pitchblende.

Progress in Airborne Radioactivity Surveying
From abstract: The objectives in the investigation of airborne radioactivity surveying during fiscal year 1951 were: 1) Establishment of a routine technique of airborne radioactivity surveying -- completed by incorporating those phases of the aeromagnetic surveying technique that were applicable; 2) Development of automatic correction of the radiation measurement for variation in distance from source -- achieved by using the radar altimeter output to modify the output of the counting-rate meter in accordance with the observed variation of radiation intensity with distance from a source; 3) Development of more efficient radiation detectors -- including large scintillation detectors.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California
From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Preliminary Report on the Results of Geobotanical Prospecting on the South Flank of Haystack Butte, McKinley County, New Mexico
Abstract: The absorber plant method of geobotanical prospecting was tested systematically over the bench formed by the Jurassic Todilto limestone on the south flank of Haystack Butte, McKinley County, N. Mex. This portion of the bench includes the largest known uranium ore body in limestone and most has been extensively drilled by private enterprise. Geobotanical prospecting was accomplished to provide control data. Comparison of the geobotanical anomalies with the available drill hole information from the mining companies and Atomic Energy Commission geologists have shown that the known ore occurrences would have been outlined by the results of the tree sampling. In addition some geobotanical anomalies are indicated in drilled areas in which ore was not reported and in areas not physically explored at the time of sampling. These anomalies may represent mineralized ground below ore grade or new ore deposits.
