This map is a 1:24,000-scale, transect-style geologic map through the southern Diamond Mountains, the northern Fish Creek Range, and the southern Mountain Boy Range. The map area also passes through the southern part of the historical, and actively explored, Eureka mining district. The map is accompanied by three cross sections, which illustrate the deformation geometry both above and below the modern erosion surface, a detailed description of map units, a summary of the geologic history of the map area, and a description of mineral deposits in the Eureka mining district. In addition, new data on the distribution, petrographic and chemical characteristics, and timing of the late Eocene Eureka volcanic center is included. This report represents a detailed analysis of the stratigraphy and structure of a classic Great Basin geological locality.
Plate 1 is the geologic map with cross section A.
Plate 2 contains cross sections B and C.
This map was prepared as part of the STATEMAP component of the National Cooperative Geologic Mapping Program in cooperation with the U.S. Geological Survey and with support from the Nevada Division of Minerals, the Geological Society of Nevada, and Timberline Resources Corporation.
