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.

From abstract: A reconnaissance radiometric survey of parts of the northwestern San Juan Mountains has revealed the occurrence of uranium-bearing ores in several mining districts in Ouray and San Juan Counties, and the occurrence of thorium-bearing veins in southwestern Gunnison County.

From abstract: Pitchblende is known to occur in the Jo Reynolds deposit, which was primarily a lead-zinc-silver ore body. The reported production in 1919 of 8 tons of high-grade uranium ore, presumably from the lowest workings of the mine, is still unconfirmed but has a fair degree of credibility.

Report discussing the geology and numerous ore deposits of the Chicago Creek area in Clear Creek County, Colorado. Prior to this report, gold, silver, copper, lead, zinc, and uranium were produced from this area.

A report about a new quadrivalent vanadium oxide from the Peanut mine named Duttonite which has the formula VO(OH)2. The mineral occurs as crusts and coatings of pale-brown transparent platy crystals.

Report discussing the W. Wilson mine, which contained quartz, chalcedony, and silicified quartz monzonite. Pitchblende was deposited in the vein of the mine and subsequently oxidized and hydrated.

Report discussing the identification of hydrothermal uranothorite from fluorite breccias in Colorado and its comparison/contrasting with other uranothorites and thorites. A description of thorium halos in fluorite is given.

Report discussing properties and uses of beryllium and beryl, an ore of beryllium produced as a by-product of mining in Colorado.

Report discussing an exploratory drilling program in the Charles T. area and vicinity during the period from November 1947 and September 1949. "The purpose of the exploration was to discover new carnotite deposits to support milling operations on the Colorado Plateau, and to appraise the uranium and vanadium resources of the area explored."

Report discussing the geology of the Wood vein and East Calhoun mine areas of Gilpin County, Colorado.

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.

Report discussing the results of a geological study of the Idaho Springs-Central City area of the Front Range mineral belt. The study was still in progress at the time of publication.

A preliminary reserve statement of Reserve Block B, of the Long Park Vicinity, located in Montrose County, Colorado.

An interim report regarding exploration of the Spring Creek Mesa Area, Montrose Country, Colorado. Concerns work done on behalf of the division of Raw Materials of the U.S. Atomic Energy Commission.

Report regarding ion chamber measurements made of the external environmental radiation in various location in the United States during the summer of 1957.

Report issued by the U.S. Bureau of Mines discussing metal mines in Colorado. As stated in the summary, "this paper describes the mineral deposits and discusses mining and milling methods and related operating conditions in an important gold, silver, lead, and zinc producing area in Ouray, San Juan, and San Miguel Counties, Colo., embracing 250 square miles" (p. 5). This report includes tables, maps, and illustrations.

A report regarding the geology and uranium deposits of the Caribou Area, in Bouler County, Colorado. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Discussing a reconnaissance carried out for uranium in parts of the San Juan Basin in New Mexico and Colorado

This report summarizes the general geology of the Slick Rock mining district and the results of drilling done by the U.S. Geological Survey during 1955.
