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.

A complex pattern of active faults occurs in the southern Amargosa Desert, southern Nye, County, Nevada. These faults can be grouped into three main fault systems: (1) a NE-striking zone of faults that forms the southwest extension of the left-lateral Rock Valley fault zone, in the much larger Spotted Range-Mine Mountain structural zone, (2) a N-striking fault zone coinciding with a NNW-trending alignment of springs that is either a northward continuation of a fault along the west side of the Resting Spring Range or a N-striking branch fault of the Pahrump fault system, and (3) a NW-striking fault zone which is parallel to the Pahrump fault system, but is offset approximately 5 km with a left step in southern Ash Meadows. These three fault zones suggest extension is occurring in an E-W direction, which is compatible with the {approximately}N10W structural grain prevalent in the Death Valley extensional region to the west.

"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).

From Introduction: "The Kingman Quadrangle, Arizona, Nevada, and California (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits.

Appendices containing uranium occurrence data in the Kingman Quadrangle, in addition to chemical analyses data to accompany a report on U.S. uranium resources in Arizona, Nevada, and California.

Appendices containing data on uranium availability in the Walker Lake Quadrangle to accompany a report on U.S. uranium resources in California and Nevada.

From Introduction: "The Reno Quadrangle, Nevada and California (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Favorable environments are those that could contain at least 100 tons U3O8 at an average grade of at least 0.01% U3O8."

Supplementary data containing uranium occurrence reports to accompany a report on U.S. uranium resources in the Reno Quadrangle, Nevada and California.

From Introduction: "The Las Vegas Quadrangle, Nevada, Arizona, and California (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

Appendix containing data on uranium availability in the Las Vegas Quadrangle to accompany a report on U.S. uranium resources in Nevada, Arizona, and California.

From Introduction: "The Vya 2º quadrangle (Fig. 1), in northwestern Nevada and small portions of California and Oregon, was evaluated to identify geologic environments and to delineate areas that have characteristics favorable for uranium deposits. Reconnaissance sampling in the Vya Quadrangle began in 1978, but final evaluation of the uranium favorability of the quadrangle was began in 1978, but final evaluation of the uranium favorability of the quadrangle was begun in June 1980."

Appendices containing data on uranium availability in the Vya Quadrangle to accompany a report on U.S. uranium resources in Nevada, Oregon, and California.

From introduction: The goals of this investigation were: (1) To estimate ground-water fluxes for use in predictions of transport of radionuclides; and (2) to study the effects of uncertainty in model parameters on these estimates.
