Impacts of climate change on landscapes of the eastern Sierra Nevada and western Great Basin
This effort was developed under a U.S. Geological Survey (USGS) initiative to sponsor science workshops focusing on various of multidiscipline, multiprogram themes in the arid Southwest. The intent was to use the workshops to explore leading edge questions, as well as to provide better communication and collaboration between USGS and other organizations and agencies. The workshop topics fall withi

A procedural manual for measurement of uranium and thorium isotopes utilizing the USGS-Stanford Finnegan Mat 262
Over the past several decades investigators have extensively examined the 238U-234U- 230Th systematics of a variety of geologic materials using alpha spectroscopy. Analytical uncertainty for 230Th by alpha spectroscopy has been limited to about 2% (2σ). The advantage of thermal ionization mass spectroscopy (TIMS), introduced by Edwards and co-workers in the late 1980’s is the increased detectabili

The Silent Canyon caldera — A three dimensional model as part of a Pahute Mesa - Oasis Valley, Nevada, hydrogeologic model
A 3-dimensional caldera model based on gravity inversion, drill-hole data, and geologic mapping offers the framework for a hydrogeologic evaluation of the Silent Canyon caldera in the central part of Pahute Mesa, Nevada.
It has been recognized for several decades that the central part of Pahute Mesa is the site of a buried caldera called the Silent Canyon caldera. Conceptually, the structural fra

Geologic map and digital database of the San Rafael Mtn. 7.5-minute quadrangle, Santa Barbara County, California
Geologic mapping of the San Rafael Primitive Area (now the San Rafael Wilderness) by Gower and others (1966) and Vedder and others (1967) did not include all of the San Rafael Mtn. quadrangle, and the part that was mapped was done in reconnaissance fashion. To help resolve some of the structural and stratigraphic ambiguities of the earlier mapping and to complete the mapping of the quadrangle, add

Shaded-relief and color shaded-relief maps of the Willamette Valley, Oregon
This Open-File Report is released as a digital map database. It includes PostScript plot files that contain images of the map sheets; the images also contain a brief explanation describing the geology and physiography of the study area. The digital map database is a compilation of newly published 10-m digital-elevation-model (DEM) data for western Oregon and represents the physiography of the Will

Petrography and physical properties of selected rock types associated with the Hayward Fault, California
This report provides brief petrographic descriptions of rock samples collected from the vicinity of the Hayward Fault, Northern California. Two groups of rock samples are represented here:
A set of six samples that were used for laboratory measurements of P- and S-wave velocity , strength, density, and porosity. This group was examined using standard petrographic microscope, scanning electron mic

Eagle Mountain Mine: Geology of the former Kaiser Steel Operation in Riverside County, California
This investigation of the Eagle Mountain Mine area, though cursory, revealed new structural, alteration, and stratigraphic relations. Eagle Mountain ores were previously an important source of iron to the western U. S. Ore (where fresh) is magnetite-pyrite rock forming two stratabound horizons virtually continuous for 11 km.
Gneissic basement rocks are overlain by two sedimentary units, separated
