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 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.

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.

A report about early proterozoic massive sulfide deposits associated with submarine mafic to felsic metavolcano rocks are present throughout central, west-central, and northwestern Arizona. Also, production data for copper, lead, zinc, gold, and silver for most of the known deposits and prospects in 13 metallic mineral districts are summarized.

A report which provides an overview of eruptions from Mount Spurr and the Alaska Volcano Observatory's response to them.

A report about the potential for Irish-type Pb-Zn deposits in a platform rocks of western Vermont; however, at Lion Hill they contain enrichments of Pb, Zn, and Cu rather than a Pb, Zn, and Ag association.

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 which records the Paleocene vertebrates, stratigraphy, and environment of deposition in the Jabal Umm Himar area.

A report about which intends to determine the feasibility of conducting a material-balance assessment of petroleum within a sedimentary basin.

A report about values for the entropy, molar volume, and for the enthalpy and Gibbs energy of formation for the elements and minerals and substances at 298.15 K.

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 that provides examples of 1990's sonar advances that help map the sea floor. Two specific devices are focused on, these are the Sea Beam bathymetric mapping system and the GLORIA sidescan-sonar imaging system.

A report that describes the geologic history of various landscapes viewed from major roadways in and around Wrangell-St. Elias National Park and Preserve.

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 new lead isotopic data on galena from within and peripheral to the Upper Mississippi Valley which make it possible to trace a pathway traversed by the mineralizing fluids beyond the boundary of the main district.

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