A 1:24,000 scale Geologic Map of the Pahroc Spring SE Quadrangle in Lincoln County, Nevada, USGS GQ1752, with 1 cross section and description of 39 units. Authored by W. C. Swadley and Peter D. Rowley in 1994. The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends.

A 1:24,000 scale Geologic Map of the Kelly Creek Area, Humboldt, Elko, and Lander Counties, in Nevada. The geologic map presented here covers much of the area of the Kelly Creek Valley, located in eastern Humboldt, western Elko, and extreme northwestern Lander Counties, Nevada. All work on the maps was performed in 1988-1991 as part of gold exploration programs of Santa Fe Pacific Mining Inc. (now Newmont Mining Corporation, which has granted NBMG permission to reproduce these maps). This information should be considered preliminary. It has not been edited or checked for completeness or accuracy. Previous mapping that covers the area completely (at 1:250,000 scale) includes the Humboldt County geology map (Willden, 1964) and the geologic map of north central Nevada (Stewart and Carlson, 1984). Hotz and Willden (1964) mapped the two quadrangles abutting to the west.

1:24,000 scale Geologic Map of The Cove Quadrangle, Nevada and Utah. Detailed geologic mapping by Elizabeth L. Miller and Phillip B. Gans in 1999. Map includes 1 cross section and description of 38 units. The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for a variety of geologic maps. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. The Snake Range, in eastern White Pine County, Nevada, is a 150-km-long, north-trending mountain range in the northern Basin and Range province. Sacramento Pass divides the range into two main parts, the northern and southern Snake Range. The Cove Quadrangle is located on the southernmost flank of the Snake Range, bordering Snake Valley to the east. Includes two of the main drainages in the range, Hendry's Creek and Hampton Creek. The Snake Range is considered a classic example of a Cenozoic "metamorphic core complex" (for example, Coney, 1979). The most prominent structural feature of the range is the northern Snake Range decollement (NSRD), a low-angle fault. Previous work includes Hose and Blake (1976) a 1 :250,000-scale geologic map of White Pine County which included the first published geologic map of all of the northern Snake Range; Nelson (1966, 1969) mapped the northern e,nd of the range as part of a regional mapping project that included the Kern Mountains and southern Deep Creek Range; studies in the northern Snake Range by geologists based at Stanford University began in 1981 by Miller and others (1983) and Gans and Miller (1983). Geologic mapping was supported by the Quadrangle mapping Program of the Geological Society of Nevada and by Echo Bay Minerals Company, Magma Nevada mining Company (now BHP), and the NBMG Mining Coop Fund.
