A paper about modal and major-element chemical data on the Mesozoic plutonic rocks of the Cowtrack Mountain and Glass Mountain quadrangles are presented in tables, maps, and diagrams.

From introduction: This report presents an evaluation of the mineral endowment (identified resources (known) and mineral resource potential (undiscovered)) of the study area and is the product of several separate studies by the USBM and the USGS.

From abstract: At the request of the U.S. Bureau of Land Management, approximately 84,165 acres of the Clover Mountains Wilderness Study Area (NV-050-139) was evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area;" any reference to the Clover Mountains Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The study area is located in southern Nevada, in Lincoln County, about 90 mi northeast of Las Vegas. No identified mineral resources exist inside the study area, although gold, silver, and copper resources are found immediately to the west at the Pennsylvania mine.

Abstract: The Behind the Rocks Wilderness Study Area (UT-060-140A) consists of 12,635 acres in Grand and San Juan Counties, Utah. The study area has inferred subeconomic resources of potash and halite in the subsurface, and sandstone on the surface. The study area has high potential for undiscovered resources of oil and gas, low potential for undiscovered uranium, copper, vanadium, gold, silver, other metals, and geothermal energy, and unknown potential for the rare-earth mineral, braitschite. There is no resource potential for potash or halite (beyond the previously mentioned inferred resources) or for coal.

From abstract: During the present study, all working were examined and representative rock and mineral samples from them were analyzed. Reconnaissance geochemical sampling of rocks, minerals, and stream sediments was conducted for the entire area.

From abstract: This report includes field investigations to evaluate the mineral resource potential of the Sweetwater Canyon Wilderness Study Area that were conducted during the summer of 1986.

From abstract: At the request of the U.S. Bureau of Land Management, approximately 85,100 acres of the Whipple Mountains Wilderness Study Area (CDCA-312) and 1,380 acres of the Whipple Mountains Addition Wilderness Study Area (AZ-050-010) were evaluated for identified mineral resources (known) and mineral resource potential (undiscovered). In this report, the Whipple Mountains and Whipple Mountains Addition Wilderness Study Areas are referred to as simply "the study area."

From abstract: At the request of the U.S. Bureau of Land Management, approximately 105,200 acres of the Turtle Mountains Wilderness Study Area (CDCA-307) were evaluated for mineral resources (known) and resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area"; any reference to the Turtle Mountain Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The wilderness study area is in southeastern San Bernardino County, Calif. Gold, silver, copper, and lead have been mined within and adjacent to the study area.

This report follows mineral-resource surveys taken at Barbours Creek and Shawvers Run Wilderness study areas in Craig County, Virginia. This report provides the findings of these studies, mineral deposits primarily.

The following report analyzes geological studies on surficial deposits in the Sheridan quadrangle of Wyoming and Montana.

The following report analyzes the geomorphic setting, the use of seismic-refraction data to delineate buried deposits, and the geotechnical analysis of aggregate samples of the sand and gravel deposits in Sheridan, Wyoming.

The following document is a collection of reports on the studies of the early Mesozoic basins of the Eastern United States. The reports are divided into four sections: reports that study the sedimentary rocks of the basins, studies of related to Jurassic igneous rocks, studies related to the geophysics, structure, and tectonics of the basins, and studies related to the mineral resources.

The following report summarizes the locations, resources, and petrophysical data of known bitumen-bearing deposits located primarily in Alabama, California, Kentucky, Texas, and Utah.
