Report issued by the Bureau of Mines over mineral characteristics, uses, and problems. Descriptions of common minerals and their uses are presented and discussed. This report includes tables, maps, and illustrations.

Report discussing the regional geology, geomorphology, structure, mineral deposits, and details of the sedimentary and igneous rocks of the Placerville Quadrangle in Colorado.

This report consists of a preliminary areal map and a brief description of the geology of the Ralston Buttes district.

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.

Report discussing the location, occurrence and chemical character of ground water in the Morrison formation near uranium-vanadium ore mineral deposits. Conclusions are included.

Report discussing information produced from aeromagnetic and regional surveys conducted in the Uravan area of Colorado. This was part of a regional geology study of the Colorado Plateau.

From introduction: Geophysical surveys have been made in the Uravan area, in southwest Colorado, with the aim of providing information on regional geology, especially on those aspects that may not be apparent from surface evidence alone. Aeromagnetic surveys were made in 1952, and regional gravity surveys were made during the summers of 1953 and 1954. Figure 1 shows the area covered. Information on surface geology was obtained from publications, from geologists working on the Colorado Plateau, and from personal observations.

A report regarding the areal geology of the Placerville Quadrangle, located in colorado. This report concerns work done on behalf of the division of Raw Materials of the U.S. Atomic Energy Commission.

From introduction: The compilation of the tectonic map of northern Colorado and northeastern Utah (area h, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps, and from unpublished data supplied by government agencies, private companies, and independent geologists. The various structures of the Foreland can be divided into three large classes to show the relation of uranium deposits to the structural pattern.

A report regarding the uranium content of ground and surface waters in Western Kansas, eastern Colorado, and the Oklahoma panhandle. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report about uranium content of water from various rocks in certain states in the United States. It attempts to locate areas in which large amounts of uranium in the water will reflect the presence of nearby uranium accumulations.

Discussing a geologic reconnaissance of the northwestern White River Plateau, in Rio Blanco and Garfield counties, Colorado.
