Indications of a Geothermal Resource West of Santa Fe, New Mexico Karl Bloor Advisors Dr. Shuo Ma and Dr. George Jiracek ABSTRACT New data from the USGS provide indications of a potential geothermal resource west of Santa Fe, New Mexico. The study area is located within the Española Basin, part of the Rio Grande rift, which has calculated heat flow between 72-109 mW/m2. Data from the USGS include temperature gradients, proposed geologic structures and ground water flow models....

Metamorphic Alteration of the Jurassic Metavolcanic Member, Winterhaven Formation, SE California; Implications for Classification and Interpreting Tectonic Setting Erik Gordon Advisor Dr. Gary Girty ABSTRACT The metavolcanic member of the Winterhaven Formation was erupted in an arc graben depression associated with extension during Jurassic subduction of the ancestral Pacific Plate beneath the California coastline. Analysis of 19 thin sections collected from the metavolcanic member...

Indications of release of constituents into groundwater in San Diego County's South Chollas Landfill Brianne Rohrer Advisor Dr. Kathy Thorbjarnarson ABSTRACT Landfills in San Diego County were not required to be lined until the 1970's, and accepted hazardous waste until the 1990's. South Chollas landfill was designed as an unlined landfill and stopped receiving waste in 1981. The by-products of trash degradation in the South Chollas Landfill produced volatile organic compounds such a...

Water Chemistry in Two Multi-Depth Monitoring Wells in San Diego, California: A Comparison of Core Extracted Pore Water Versus Multiple Depth Well Samples Heather O'Brien ABSTRACT In 2001, the United States Geological Survey, in partnership with Sweetwater Authority and the City of San Diego, began a study to assess the geology and hydrology of the San Diego area. In addition to collecting surface water samples, seven multi-depth wells have been installed by USGS into the San Diego...

Geochemistry and Petrogenesis of mid- Miocene Volcanoes from the Ancestral Cascades of Northeastern California Steven Warner ABSTRACT Several well-preserved, mid- to late Miocene volcanoes in northeastern California could well have an origin associated with the late Tertiary development of the ancestral Cascades volcanic arc. To assess this possibility, we have analyzed seventeen samples from the Spanish Springs Peak volcano and ten additional samples from four nearby volcanoes for...

Straightening of the northern San Jacinto Fault, California: Is the San Jacinto fault competing with the San Andreas Fault for "Big Kid on the Block"? Gayatri Indah Marliyani M.S. Candidate Department of Geological Sciences San Diego State University Advisor Dr. Thomas Rockwell Wednesday, April 27th, 2011 -------------------------------------------------------------------------------- ABSTRACT New CPT and trench observations along the Claremont Fault at Mystic Lake indicate...

Short magma residence times for Kilauea Volcano based on high-precision Pb isotope ratios Daniel Heaton M.S. Candidate Department of Geological Sciences San Diego State University Advisor Dr. Aaron Petruszka Monday, April 25th, 2011 CSL 422, 2:00pm -------------------------------------------------------------------------------- ABSTRACT We present new high-precision Pb isotopic analyses of 46 historical Kilauea summit lavas (1823-2008). These data are used here to investigate...
