[Plates I-X]

Description: Illustrations accompanying a report investigating the locations of vanadium-bearing phosphatic shale in West-Central Wyoming and Southeastern Idaho. The set includes seven maps (Plates I and V-X) showing the location of rock formations in the area and three charts (Plates II-IV) showing the correlation between the occurrence of vanadium deposits and the thin persistent beds of phosphate rock, oolite, siltstone, dolomite, and limestone with which they are interbedded.

Table IV - Estimated Reserves of Vanadium-Bearing Rock In Areas of Extraction

Description: Table showing the estimated reserves of vanadium-bearing rock in the Paris-Bloomington, Montpelier, Sublette Ridge, Swift Creek, and Strawberry Creek - Greys River Divide extraction areas in west-central Wyoming and southeastern Idaho. Indicated tonnage and inferred tonnage values are given for each area in millions of tons, along with the percentage of vanadium ore rock, maximum and minimum thickness, and average thickness of the rock in the extraction area.

The Determination of Thorium in Uranium-Thorium Alloys, Using Cupferron

Description: Technical report describing that the use of controlled amounts of carbonate, acting both as complexing agent buffer led to a fairly satisfactory procedure for the determination of Th in Th-U alloys, using cupferron. The alloy, dissolved in NHO2, in the presence of HF, is treated with H2SO4 and the mixture is evaporated in SO2 fumes. The solution is diluted and (NH4)2CO2 is added. Th is precipitated from this solution with cupferron. The precipitate is weighed as ThO2 after ignition. An accura… more

The Metabolism of Thorium, Protoactinium, and Neptunium in the Rat

Description: From abstract: "The distribution of carrier-free thorium, protoactinium and neptunium in the rat following intramuscular and oral administration has been studied. Oral adsorption for all three is negligible. Following parenteral administration, the skeleton is the organ showing the highest degree of prolonged and selective localization."

Procedures for the Separation of Products Resulting From Bombardment of Heavy Elements

Description: Technical report that attempts to bring together the various chemical procedures which proved most useful in studying the results of cyclotron bombardment or small scale neutron bombardments of heavy element targets. The report is limited to the elements of the "actinide", or second rare earth series, starting with thorium and including the newly discovered elements of atomic number 95 and 96. Every attempt is made to include all details necessary so this report can serve as a practical labora… more

The Application of Tracer Techniques to the Determination of Uranium Extraction Coefficients

Description: Abstract: This report deals with the development of a method using tracer technique for determining uranium extraction coefficients on solutions of low uranium concentration. It was found that extraction coefficients could be determined on systems containing as low as one part per million uranium using 1900 level uranium as the tracer. Results of several extraction series are presented in which aluminum nitrate is used as the salting agent and dibutyl carbitol the organic extractant.

Summary of Research on Experimental Refractory Bodies of High-Melting Nitrides, Carbides, and Uranium Dioxide

Description: Abstract: A procedure for the preparation of the nitrides and carbides of several metals and the preparation of the refractory bodies from them is described. The investigation shows that reasonably strong and dense bodies can be prepared from these materials as well as from UO₂. Evidence showing the tendency toward instability at high temperatures of Be₃N₂, TaN, and ThN is presented. Evidence is also given indicating that the hexagonal structure reported by others for TaN is actually that for T… more

Summary of the Research Progress Meeting of March 9, 1950

Description: The design of the present time of light mass spectrograph is similar to that of the isotron devised some time ago for isotope separation. The spectrograph will employ the time of flight principle only for the isotopic analysis of small samples.
