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.

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.

The following report documents the geological mapping of the Harpers Ferry quadrangle, Virginia, Maryland, and West Virginia, from between 1989 and 1990.

The following report documents results taken from a reconnaissance geochemical survey that was conducted in the northwest-trending Alexander terrane, Gravina-Nutzotin overlap assemblage, and Taku terrane in southeast Alaska in the Craig and Dixon Entrance quadrangles and the western edges of the Ketchikan and Prince Rupert quadrangles.

The following report is a mineral resource assessment of Coronado National Forest of southeastern Arizona and southwestern New Mexico, formed by geologic, geochemical, and geophysical data.

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 presents geochemical data results of 34 elements in 951 samples of altered and mineralized rock samples from mines, prospects, dumps, and drillholes in the Tonopah quadrangle, Nevada.

This report studies the fluvial-terrace deposits in northwestern Tennessee with the intention of establishing a means of correlating disjunct terrace segments along the Obion River that is independent of terrace height, to document the stratigraphy of selected terrace deposits, and to estimate their numerical ages.

This report covers the study of thermal maturity of sedimentary basins in Alaska taken place in the early 1990s.

The following report interprets the geologic history of the Paducah quadrangle, focusing on depositional and tectonic evolution, particularly tectonic events that influenced sedimentation.

This report follows the investigation and findings of mineral resources in the Notch Peak Wilderness Study Area, Utah.

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 presents detailed lethologic and conodont biostratigraphic data from four measured sections in the lower part of the Oquirrh Group in the Oquirrh Mountains of Utah and the Deep Creek and Samaria Mountains of Idaho.

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.

From introduction: "This report illustrates a method for delimiting prospective placer districts in the United States by use of National Uranium Resource Evaluation (NURE) Hydrogeochemical Stream Sediment Reconnaissance (HSSR) geochemical data and adjunct airborne spectral gamma-ray radiation data."

Proceedings of a workshop held in February 1990 called "Tertiary Stratigraphy of Highly Extended Terranes, Southern Basin and Range" at the Desert Research Center of the California State University System, Soda Springs, near Baker, California. This volume is a collection of stratigraphic data and interpretation.

The following report analyzes the geological features of a 6-km by 0.3-km strip of glacially polished rocks of the Nelchina River Gabbronorite located in the eastern part of the Anchorage quadrangle.

The following report follows the first research drilling study on a geyser. Whistle, a nearly dormant geyser in the upper geyser basin in Yellowstone National Park, Wyoming, has been proven to depend its water supply on deep overpressured water that's a far more extensive system than surface measurements can determine.

The following report provides information for the public good about the origin, quality, and quantity of mineral resources world-wide. This Bulletin reports progress on some of the current activities of the Office of Mineral Resources and reflects the necessity for an international perspective regarding mineral resources and research technology.

The following report is the second compilation of reports describing the geology of the Basin and Range to Colorado Plateau Transition (BARCO) area.

Abstract: "Precambrian metavolcanic rocks north and south of the village of Granite, Wyoming, belong to a sequence of isolated metavolcanic and metasedimentary masses in the Sherman Granite of the southern Laramie Mountains. Similar rocks lie to the west, in the Precambrian uplifts of the southern Medicine Bow Mountains and Sierra Madre. A major fault system, the Cheyenne belt, splits these two ranges into northern and southern domains, and may constitute a suture along which Early Proterozoic islands arcs collided with an Early Proterozoic passive margin. Projection of the Cheyenne belt into the Laramie Mountains suggests that the study area, which is 65 kilometers south of the proposed suture, comprises a distinct volcanic arc with a unique chemistry or age. However, chemistry of the volcanic rocks of the study area as determined as so far does not differ significantly from those of the Medicine Bow Mountains and Sierra Madre."
