From Abstract: "This report presents the results of field reconnaissance and office study of available data pertaining to the Cedar Mountains area, Emery County, Utah, and is part of a series of reports synthesizing the geologic relations of uranium deposits in all formations on the Colorado Plateau."

This report presents field reconnaissance results and office study of available data pertaining to the Cedar Mountain area, Emery County, Utah, and is part of a series of reports synthesizing the geologic relations of uranium deposits in all formations on the Colorado Plateau.

A report which presents the results of a study of the uranium resources of the Green River and Henry Mountains districts, Utah, and is part of a series of similiar reports synthesizing the geologic relations of uranium deposits in all formations on the Colorado Plateau.

The following report covers the study of the area described in this report that is part of the White Canyon mining district, San Juan County, Utah. Upon this investigation, uranium deposits were discovered and analyzed.

The following report covers measurements of electrical resistivity and dielectric constant that were made on parts of 27 cores from the Morrison formation in the Colorado Plateau uranium province as part of a program to obtain basic data on the physical properties of the rock in and near uranium-mineralized zones.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

Abstract: Uraniferous rock was discovered in the Phillips mine-Camp Smith area in 1953. Precambrian rocks of the Hudson Highlands of the New England physiographic province underlie the area.

Report discussing uranium that was discovered in uraniferous rock in the Phillips mine-Camp Smith area of New York in 1953.

The following report studies a rare-earth deposit in the Scrub Oaks iron mine, Morris County, New Jersey, that was mapped and sampled in the 1955.

A report about the ages of the four great batholiths in the western United States.

Abstract: "A procedure for the determination of thorium in the concentration range of 0.2 to 10 parts per million ThO2 in felsic or mafic rocks. Thorium is extracted by mesityl oxide and purified by iodate precipitation from nitric acid medium containing tartaric acid and hydrogen peroxide. The thorium is determined spectrophotometrically with thoron from meso-tartaric acid medium."

From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

Discussing the geology and ore deposits of the Kern River Uranium Area, located in Kern County, California

The following report covers investigations on the geology of the Kern River uranium area in Kern County, California, as well as the small uranium ore deposits erratically distributed along fractures.

The following report covers a reconnaissance for uranium and thorium in Alaska during the 1954 field season that consisted principally of a study of the radioactive beach placers east and west of Cape Yakataga, and ground and airborne radiometric traverses of portions of Kodiak Island and adjacent islands.

The following report summarizes a reconnaissance for uranium in Alaska during 1955 that included airborne radiometric traverses, examination of radioactivity anomalies found during the airborne traverses, examination of prospector leads, and examination of areas that seemed geologically favorable for the occurrence of uranium.

Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."

A report regarding reconnaissance for Uranium in Northern Texas and Southern Oklahoma. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report pertaining to uranium which has been found in two stratigraphic zones in rocks of permian age in northern Texas and south-central Oklahoma.

The following report covers a chemical study that was made of the Salt Wash member of the Morrison formation of Jurassic age in the Jo Dandy area, Montrose County, Colorado in 1954. The chemical study was made to investigate the distribution of elements in the host rocks with emphasis on the pattern of variation as related to the position of known ore bodies, and to determine average concentrations of some of the elements in the major rock types.

The following report covers reconnaissance studies of beryl-bearing pegmatite discovered in Nevada and in part of Mohave County, Arizona.

From Introduction: "The primary purpose of this work was to summarize and bring up to date the information on beryl resources as gained from investigations during 1942-45, to examine in detail certain beryl-bearing pegmatites discovered and developed in recent years, and to study other pegmatites and groups of pegmatites known or suspected to contain beryl."
