Geometry and Morphology of Cracks in Saprock: Implications for Ground Shaking Taylor Carrasco B.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. Gary Girty -------------------------------------------------------------------------------- ABSTRACT Lying between the Elsinore and San Jacinto faults is a band of precariously balanced rocks first identified by J. Brune and colleagues. Peak accelerations during ground shaking events on the San...

SDSU Geological Sciences Webinar - Larry Buchanan

submitted by: tcarrasc
Geology of the San Cristobal Deposit Dr. Buchanan earned his PhD in Economic Geology in 1979 and taught university level geology for several years before the romance of prospecting drew him back to the field. After several notable gold and silver discoveries, he capped his career in 2006 by winning the coveted Thayer Lindsley Award for the San Cristobal silver discovery. Larry will talk about that Discovery. He will also describe the transformation of the village and living conditions...

Forearc Basin Analysis of the Late Jurassic-Early Cretaceous Eugenia Formation; New Mapping and Provenance Analysis in the Northern Vizcaino Penninsula, Baja California Sur Christopher Kohel M.S. Candidate Department of Geological Sciences San Diego State University The Late Jurassic-Early Cretaceous Eugenia Formation represents an enigmatic part of the Vizcaino Peninsula forearc stratigraphy. Eugenia sub-basins on the Vizcaino Peninsula are broadly correlative to the Jurassic forearc...

Paleoseismology of the Southern Clark Strand of the San Jacinto Fault Zone, Southern California Michael Buga M.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. Tom Rockwell We present results from a new paleoseismic trench site on the Clark strand of the San Jacinto Fault Zone in Clark Lake, western Salton Trough, southern California. The trench results suggest that most late Holocene slip along the Clark fault at Clark Lake is localized within a...

New Insights Into The Relationship Between Fault Segmentation And Earthquake Rupture: The North Anatolian Fault, Turkey Gulsen Ucarkus Post-doctoral Researcher Scripps Institution of Oceanography -------------------------------------------------------------------------------- Strike-slip faults are often segmented by step-overs resulting in a variety of deformation styles such as constraining bends, releasing bends and rotational deformation. These step-overs or discontinuities...

Cataclysms on the Columbia, the Great Missoula Floods Scott Burns Department of Geology Portland State University One of the greatest set of geological events to ever have occurred in North America was given the name, the Missoula Floods. The floods originated when an ice dam broke in upper Idaho liberating waters impounded in back of it in Montana, scouring out large sections of eastern Washington and the lower Columbia River drainage basin. The talk will focus on the incredible story...

The Enigmatic Satellites of Saturn Gary Peterson Professor Emeritus Department of Geological Sciences San Diego State University Saturn, everyone's favorite planet, is the second-largest of the outer giant gas planets and has the lowest density (0.7) of any planet. The others gas planets are about 1.5. In addition, Saturn has the largest satellite (Titan) in the Solar System. Titan is about the same size as Mercury of the inner Solar System. How can this be? It is suggested that...

Geochemical assessment of mixing advanced treated wastewater and groundwater in the Harmony Grove Basin, Southern California Anthony Fisher ABSTRACT The Harmony Grove basin aquifer is located in San Diego California. This location is being sought after by the Rincon del Diablo Municipal Water District for storage of advanced treated wastewater (ATW). After storage, pumping of groundwater is proposed for potable reuse. The project consultant sampled and analyzed groundwater chemical...
