Conditions of the Formation of Fluorite in Sedimentary Rocks (The Fluorite System)
From translator's abstract: "The formation of fluorite in sedimentary rocks has been investigated by studies of fluorite equilibria in different solutions. Determinations at different temperatures were made on the solubility of crystalline CaF2 in chemically pure water, in aqueous solutions of components of seat water...at different concentrations, and in the sea water itself at degrees of salinity varying from normal to a 15-fold concentration."

The Fluorapatite System of Equilibria in the Conditions of Formation of Sedimentary Rocks
From translator's abstract: "As part of unified research on the behavior of the fluoride ion in sedimentary rocks, the present study deals with the system CaO-P2O5-HF-H20 at 25 degrees C. under conditions of sea sedimentation. The precipitated phases, their fields of crystallization and stability, the fluorine-phosphorus coefficient, and the isomorphism of fluorhydroxl ions in the apatite lattice are considered and illustrated by orthogonal projections."

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits
From abstract: The Geological Survey has been studying the geology of uranium and thorium continuously since 1939, when it began a comprehensive investigation of the vanadium-uranium deposits of the Colorado Plateau. Greatly increased demand for uranium arising from the advent of controlled fission in 1942 resulted in widening of the study in 1944 to include other possible sources and in further expansion on behalf of the U. S. Atomic Energy Commission since 1947. The wide variety of materials investigated in this study are embraced by five somewhat arbitrary groups of related types of deposits as follows: (1) Igneous rocks, pegmatites, veins, and related deposits; (2) Deposits in sandstone of carnotite, copper-uranium, and other minerals; (3) Other consolidated sedimentary rocks; (4) Placers; and (5) Natural fluids.

The Permian Phosphate Deposits of Western United States
From abstract: The Permian marine phosphorite deposits of the western United States were laid down in the Phosphoria formation and its partial stratigraphic equivalents over an area of about 135,000 square miles in Montana, Idaho, Wyoming, Utah, and Nevada. The deposits in the eastern part of the field lie on the western margin of the structurally simple North American craton.

Domestic Phosphate Deposits
From abstract: Incomplete but recently partly revised estimates indicate the presence of about 10 billion tons of phosphate deposits in the Urited States that is minable under present economic conditions. Deposits too lean in quality or thickness to compete with those in the western and southeastern fields probably contain tens of billions of tons.

Progress Report on Investigations of Western Phosphate Deposits
From abstract: A comprehensive investigation of the western phosphate deposits, in progress since 1947, involves a study of the Phosphoria and Park City formations over an area of about 135,000 square miles in the states of Montana, Idaho, Wyoming, and Utah0 It was undertaken to acquire more data on the thickness, composition and quality, structure, and distribution of the deposits--data that would help industry select deposits suitable for mining and permit estimation of reserves, evaluation of potential byproduct elements, and establishment of the origin of the deposits.

Results of Diamond Drilling and Geologic Investigation of the Shirley May (Garo) Uranium Deposit, Park County, Colorado
From abstract: The Shirley May (Garo) uranium deposit near Garo, Park County, Colo. , consists of tyuyamunite and carnotite that occur as disseminations and as fracture fillings in three beds of medium- to coarse-grained sandstone. The sandstones are in the Maroon formation of Permian age, This deposit was explored by means of 12 core-drill holes, totalling 2,003 feet.
