The following report is preliminary in nature, discussing and analyzing traces of uranium in apatite and phosphorite.

This report discusses an apparatus that has been constructed to record the thermoluminescence of a mineral in the form of a powder or a single crystal at temperatures from -100 C to +400 C.

From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

The following report covers investigation work done on the distribution of thick deposits of salt that had occurred in the Paradox member of the Hermosa formation of Pennsylvanian age in an area nearly 12,000 square miles of southwestern Colorado and southeastern Utah.

A report regarding the distribution and thickness of salt in the paradox basin of southeastern colorado and southeastern Utah. This report concerns work done on behalf of the Division of research of the U.S. Atomic Energy Commission.

A report which records the results of experiments dealing with the synthesis of carnotite and its alkali analogues. The work was primarily concerned with the preparation of single crystals suitable for detailed structural analysis, though some insight into the chemistry of the precipitation of carnotite was obtained.

The following report summarizes briefly current knowledge of the association of uranium with petroleum and asphalts and presents analytical data compiled during the course of investigations by the U.S. Geological Survey on behalf of the Division of Raw Materials, U.S. Atomic Energy Commission. The primary concern of this paper is focused on uranium and petroleum and natural asphalts.

Discussing uranium in petroleum and rock asphalt

The following report covers the Petrographic study of Early Cretaceous age sandstone beds in the Fall River formation and the Fuson-Lakota formations, as well as Late Jurassic age beds in the underlying Unkpapa and Morrison formations along the western side of the Black Hills.

A report regarding petrographic study of sandstone of the Inyan Kara group and associated rocks in the Black hills, Wyoming and South Dakota

From abstract: The uranium deposits in the Carlile quadrangle, southwestern Crook County, Wyo., are in relatively flat-lying sandstone beds in the lower part of the Inyan Kara group of Early Cretaceous age. The Carlile mine has the largest deposit in the quadrangle; the ore minerals are carnotite and tyuyamunite associated with carbonaceous material in a sandstone lens.

The following report presents a generalized description of the uranium deposits discovered in the northern Black Hills.

The following report covers detailed investigations on botanical methods of prospecting for uranium that have been developed on the Colorado Plateau by the U.S. Geological Survey.

"The Purpose of this paper is to present a preliminary discussion of the stratigraphy of the park city and phosphoric formations with special emphasis on the phosphatic parts and to discuss the distribution of phosphate in Utah. The Mississippian deposits are discussed only briefly because of the lack of new data concerning them"

The following report presents a preliminary discussion of the stratigraphy of the Park City and Phosphoria formations with special emphasis on the phosphatic parts, and to discuss the distribution of phosphate in Utah.

The following report describes the study of the hydrous uranium-molybdenum mineral umohoite discovered in the Lucky Mc mine, Wyoming.

The following report covers the study of the Chattanooga shale and Maury formation found between the Nashville Basin and the surrounding Highland Rim.

A report about the amount of lead retained in the ash of lead-bearing carbonaceous material which is essentially independent of the method of ashing.

The following report is based mainly on information obtained from lithologic and gamma-ray logs of drill holes in the Lakeland Highlands area and Clark James-South Ridgewood.

This report analyzes the characteristics of three vanadium-uranium ores of the Colorado Plateau by prevalence of a number of low-valence vanadium oxide minerals, usually occurring as fine-grained mixtures. The ores being analyzed are haggite, doloresite, and duttonite.

The following report is a statement of the Geological Survey's progress on the investigation of the fundamental geology, mineralogy, and geochemistry of uranium and other radioactive materials with the intention of discovering and delimiting areas favorable for the future production of uranium and other radioactive ores. This report covers the period from December 1, 1956 to May 31, 1957.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

The following report covers geological studies on the USGS and Rainier tunnel areas in the Nevada Test Site.

A report about drill holes in uranium in the Todilto limestone of Late Jurassic age near New Mexico which does not yield duplicate gamma-ray logs when probed at different times.
