A report about nomenclature related to planets in the solar system. It contains detailed information about all names of topographic and albedo features on planets and satellites.

A report about how topographically driven ground-water flow and other processes that involve dewatering of basins fail to account for the temperatures indicated by fluid inclusion and sulfur isotope studies in the Upper Mississippi Valley zinc-lead district on the northern edge of the Illinois Basin.

A report about the carbonate-evaporite sequence of the lower part of the Mississippian St. Louis Limestone. There is organic rich strata that may be good to excellent hydrocarbon source rocks.

A report about fossils in Saudi Arabia. The report discusses locality, higher taxon, and specimens within the taxon from a given locality.

A report about some of the environmental impacts of the Summitville open-pit mine that was abandoned after 1992.

Abstract: The U.S. Geological Survey and the Corporación Venezolana de Guayana, Técnica Minera, C.A., conducted a cooperative mapping, exploration, and mineral resource estimation study in Venezuela from 1987 to 1992. The work was conducted in the Venezuelan Guayana Shield, an Archean to Early and Middle Proterozoic craton in southern and eastern Venezuela of almost 415,000 km2 that is mostly covered by jungle and savanna. Results obtained from this project contribute a new understanding of the geology and evolution of the Venezuelan Guayana Shield and the nature of its mineral occurrences. Personnel from Técnica Minera, C.A., were trained both in the field and in the office to conduct modern mineral exploration and geologic mapping and research programs. This five-year project was supported financially by the Corporación Venezolana de Guayana.

The following report provides detailed analyses of two 300-meter cores from upper Turonian to lower Campanian strata of the Straight Cliffs Formation, Kaiparowits Plateau, Kane County, Utah.

Report containing a series of chapters discussing the geologic and mineral resources of the Hailey Quadrangle and Western part of the Idaho Falls Quadrangle in Idaho.

From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.

From abstract: This report attempts to identify areas where geologic conditions for the Mississippi Valley-type (MVT) deposits are favorable.

From abstract: This report is about the geology of pre-Pennsylvanian rocks in the Paradox basin and its adjacent areas--such as the Mississippian strata, the Upper Devonian rocks, and the Upper Cambrian--in southeastern Utah and southwestern Colorado.

From abstract: This report is about six gas samples that were obtained from the Mississippian Leadville Limestone in the McElmo field, Colorado, and the Lisbon field, Utah. These samples were recorded to contain a high reading of carbon dioxide and the report investigates these results.

From introduction: This report supplements similar reports prepared for the four 7.5-minute quadrangles that cover the Turkey Creek caldera and geologic map of the caldera.

From abstract: This report contains the analysis of the southern part of the Canadian Shield and the subsurface of the southern interior platform where they comprise two Archean cratons and three Early Proterozoic collisional orogens.

The following report analyzes the geology of the Waterford quadrangle and the Virginia part of the Point of Rocks quadrangle.

This report follows the isotopic geolchronological study of the Leadville quadrangle in west-central Colorado. The dates provided offer important information on the age of emplacement of Proterozoic, Late Cretaceous, and Tertiary igneous rocks.

The following report presents measured sections and lithostratigraphic correlations of the units in the order to document a syntectonic unconformity in order to understand the tectonic history of the area.

The following report follows a geochemical survey and its findings in the Valdez quadrangle in south-central Alaska.

The following report focuses on the geology of the Tertiary volcanic rock formation in the Sleeper gold-silver deposit of Nevada and develops a framework for exploration and genetic models.

The following report presents geological data taken from studies made on the mineral and energy resources in the surface and subsurface within the Roswell Resource Area in east-central New Mexico.
