New at NBMG: Geothermal core from Rye Patch area–new Open-File Report
Open-File Report 11-10
Descriptive Logs, Skeletonized Samples, and Photographs of Core from Presco Energy’s Thermal Gradient Wells P 3-1, P 10-1, and P 32-2 in the Rye Patch Area, Pershing County, Nevada
by David A. Davis
This report, which is available as an online document at www.nbmg.unr.edu, describes the selective sampling (skeletonizing) of diamond drill core from three geothermal wells drilled in the Rye Patch area. The skeletonized samples can be viewed at the Great Basin Science Sample and Records Library (GBSSRL), and the lithologic descriptions of the core, photographs of the entire core, and photographs of the individual samples are posted online.

New at NBMG: Map 174: Geologic map of the Caetano caldera, Lander and Eureka counties, Nevada
by Joseph P. Colgan, Christopher D. Henry, and David A. John
2011
A 1:75,000-scale, color geologic map of the 34 Ma Caetano caldera, Lander and Eureka counties, Nevada with descriptions of 41 geologic units and one cross section. Accompanying text includes full unit descriptions and references. More than 100 percent extension beginning in the middle Miocene tilted the caldera into a set of approximately 40-degree east-dipping fault blocks that provide exceptional exposures of the entire caldera to its floor, including Paleozoic sedimentary rocks and pre-caldera volcanic rocks in the floor, intracaldera Caetano Tuff up to 4 km thick, ash-flow tuff feeder dikes, caldera collapse breccias, post-collapse resurgent intrusions, and the caldera structural margin and topographic wall.
35X27-inch color plate and 10 pages of text
