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...

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...

The Nature Explorers Lassen Volcanic Region Expedition Part 13 of 13

submitted by: thenatureexplorers

We travel to the Lassen Volcanic Region to explore this high subalpine montane region just below the tree line, made up of vast conifer forests and rocky outcroppings. Here we observed a huge array of butterflies, moths, bees, and other insects pollinating flowers to ensure their continued survival.
