From introduction: This bibliography consists of annotations or abstracts of selected reports that pertain to the geology and occurrence of uranium in marine black shales and their metamorphic equivalents in the United States.

Introduction: In this bibliography emphasis is placed on reports dealing with the uranium contents and radioactivity of native bituminous substances rather than on mineralogical and chemical studies of these substances.

From introduction: The gravity survey of the Nevada Test Site and contiguous areas of southern Nevada and southeastern California has been made by the U.S. Geological Survey on behalf of the U.S. Atomic Energy Commission. The objective of this study is to delineate and interpret gravity anomalies and regional trends so that the configuration and depth of the buried erosional surface of the Paleozoic rocks may be determined.

From abstract: The Merry Widow claim is near the center of sec. 22, T. 20 S., R, 15 W, New Mexico principal meridian, about 1 mile west of White Signal, Grant County, N. Mex. Secondary uranium minerals were discovered in the White Signal district in the early 1920's although several mines in the district had been worked previously for gold, silver, and copper. The writers mapped the Merry Widow claim in 1950, collected 133 samples, and logged the core from one diamond-drill hole on the Merry Widow claim.

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.

From introduction: The investigations that are the subject of this report were to appraise the uranium resources of the Red Desert area, and to accumulate data concerning the geology of uranium. Knowledge of the genesis of the schroeckingerite is necessary for a clear appraisal of the deposit.

From introduction: This report is a summary of geologic information obtained by the USGS at Dolomite Hill, Nevada.

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.

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.

A report about the occurrence, distribution, and quantities of beryl and other strategic minerals in pegmatites located in the Newry Hill area, Maine.

Report discussing the results of diamond drilling and geological investigation of the Shirley May Deposit, also known as the Garo uranium deposit, which is about 3/4 mile south of Garo, Park County, Colorado.

Report discussing "a direct comparison of helium and lead in nonmetamict zircon crystals".

Report discussing the U.S. Geological Survey's investigation of radioactive materials in the Serpentine-Kougarok on the Seward Peninsula of Alaska.

From abstract: "In this report the mineralogy and uranium contents of southeast phosphates are discussed with reference to the lithologic units of the Hawthorn and Bone Valley formations and to waste slimes. In addition, the immediate problem of sampling leached-zone rock for process development studies is discussed and plans for future work (fiscal 1953) are presented."

Report discussing the investigation of uraniferous pyrobitumen deposits found at mining sites at the Weatherly and Robinson properties by Placerville, Colorado.

The following report summarizes descriptive geological and lithological data for the U12i tunnel system in the Nevada test site.

Report discussing the occurrences of uranium on the Merry Widow claim near White Signal, Grant County, New Mexico. "The writers mapped the Merry Widow claim in 1950, collected 133 samples, and logged the core from one diamond-drill hole on the Merry Widow claim."

Report discussing a study of samples taken from "commercially important coal beds and associated rocks in the Pottsville, Allegheny, and Monongahela series of the Pennsylvanian system". The report contains sections on the scope of the investigation, stratigraphy, radioactivity and uranium content of the coal beds and carbonaceous shale, and descriptions of the rock exposures examined.

Abstract: "Calculations have been made of alpha star populations in loaded nuclear emulsions. Equations are presented for calculation of star types for each significant emitter in the three naturally radioactive series. The application of five-branched star populations as a method of quantitative analysis for microgram amounts of thorium is proposed."

From abstract: "Sediments of the inner part of the southern Atlantic Coastal Plain have been sampled and examined for monazite." The report provides sections on general geology, field and laboratory methods, distribution of monazite, and other mineral products.

Report discussing the U.S. Geological Survey's investigation of carnotite deposits found at Club Mesa, Colorado.

Report discussing studies on the molybdenum blue reaction and the determination of phosphorus in waters containing arsenic, germanium, and silicon. Experimental methods and data are included.
