Analyses of Tipple and Delivered Samples of Coal: (Collected During the Fiscal Years 1948 to 1950 Inclusive)

Description: From Forward: "This bulletin is the first of a new series, which includes analyses of only tipple and delivered coal. It covers samples collected throughout the United States from July 1, 1947 to June 30, 1950 (fiscal years 1948-50). It is planned that future publications of this series will cover a period of one fiscal year only and be issued as soon as possible after June 30 of each year."

Experimental Simulation of Plateau Type Uranium Deposits

Description: From abstract: Experimental simulation of Colorado Plateau type uranium deposits is divided into seven parts. The first three summarize the essential features of geological occurrence for the ores. The last four parts outline the results of experimental investigation arranged according to each geological group of features influencing mode of occurrence.

Geophysical Investigations on the Gramlich Group, Paradox District, Montrose County, Colorado

Description: 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.

Uranium Occurrences in the Golden Gate Canyon and Ralston Creek Areas, Jefferson County, Colorado

Description: From abstract: Pitchblende, associated with base-metal sulfides, has been found at eight localities in the northern part of Jefferson County, Colo., in shear zones that cut pre-Cambrian metamorphic and igneous rocks, chiefly hornblende gneiss, biotite schist, and granite pegmatite. The pitchblende deposits, with one exception, are in major shear zones that contain vein-like bodies of carbonate-rich breccia. The breccia bodies range from 1 to 5 feet in thickness and are related probably to the L… more

Occurrences of Uranium-Bearing Minerals in the St. Kevin District, Lake County, Colorado

Description: From abstract: Two hundred and seventy-one prospect pits, mine dumps, or mine workings within the Sugar Loaf-St. Kevin mining districts and vicinity, were tested for radioactivity by the U. S. Geological Survey in 1951 during six weeks of investigation on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. One hundred and twenty-two weak radioactivity anomalies were found in the St. Kevin district and vicinity, and eight slight anomalies were noted in"-the Sugar Loaf … more

Results of Reconnaissance for Radioactivity in Parts of the Alma District, Park County, Colorado

Description: Abstract: Pitchblende was discovered in July 1951 in the Alma mining district, Park County, Colo0 , by the U0 S. Geological Survey acting on behalf of the U. So Atomic Energy Commission. The pitchblende is associated with Tertiary veins of three different geologic environments: 1) veins in pre-Cambrian rocks, 2) the London vein system the footwall block of the London fault, and 3) veins in a mineralized area east of the Cooper Gulch fault. Pitchblende is probably not associated with silver-lead… more

General and Engineering Geology of the Wray Area, Colorado and Nebraska

Description: From abstract: Most of the formations in the Wray area are fair foundation materials, although good construction materials are scarce. The gravel of the Grand Island formation and the gravels in the Ogallala formation contain large quantities of clay, silt, sand, and calcium carbonate, and have very few pebbles larger than one-half inch in diameter.

Preliminary Report on 1952 Field Investigations in Wet Mountains, Colorado

Description: From page 3: A metallogenic province containing thorium in veins in pre-Cambrian rocks along the western slope of the Wet Mountains, Colo. found by the Reconnaissance Group of the U. S. Geological Survey during the summer of 1950,was revealed by the discovery during fiscal-years 1951-1952 of seventeen radioactive deposits scattered along a north-northwest linear distance of twenty miles. All the thorium occurrences were found within terrain that has never been geologically mapped. Three of the … more

Identification and Occurrence of Uranium and Vanadium Minerals From the Colorado Plateaus

Description: Abstract: "This report, designed to make available to field geologists and others information on identification and occurrence of uranium minerals of the Colorado Plateaus, contains physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis of 24 uranium and 17 vanadium minerals. Also included is a table giving the optical properties of uranium minerals and a list of locations of mines from which the minerals have been identified."

Reconnaissance During 1952 for Uranium-Bearing Carbonaceous Rocks in Parts of Colorado, Utah, Idaho, and Wyoming

Description: The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Geologic Aspects of the Resource Appraisal of Uranium Deposits in Pre-Morrison Formations of the Colorado Plateau

Description: The following report covers a reconnaissance resource appraisal in pre-Morrison formations, particularly the Shinarump conglomerate, on the Colorado Plateu and adjoining regions during December of 1951. This report is preliminary in nature and the ideas are presented as a hypothesis to be tested by future work.
