Petrology of the Santiago Peak Volcanics, San Diego County, California: Jerehme Acosta, B.S. Candidate, Department of Geological Sciences, San Diego State University - The Santiago Peak Volcanics (SPV) is exposed discontinuously in a belt along the western side of the Peninsular Ranges batholith in southern and Baja California. The SPV is intruded by ~125-100 Ma intrusions of the batholith and unconformably overlain by Late Cretaceous forearc basin strata of the Rosario Group. The SPV has...

Carbonated Oceans

submitted by: ucsandiego

As carbon dioxide is pumped into the atmosphere, about one-third of the excess is taken up by the oceans, where it converts to an acidic form with potentially dangerous ecosystem consequences.

The Recent Prehistoric Geochemical Evolution of Summit Lavas From Kilauea Volcano, Hawaii: Dale Burns, M.S. Candidate, Department of Geological Sciences, San Diego State University - Lavas from Kilauea Volcano display rapid geochemical and isotopic variations (e.g., 206Pb/204Pb or Nb/Y ratios) on a time scale of decades to centuries. The wall of Kilauea Caldera at Uwekahuna Bluff exposes a sequence of recent prehistoric, caldera-filling lavas (erupted mostly between AD 900-1400). Here we...

Stratigraphy and structure of the Miocene Bear Canyon Conglomerate, Imperial County SE California: Evidence for the episodic growth of the Chocolate Mountains anticlinorium: Krista Muela, B.S. Candidate, Department of Geological Sciences, San Diego State University - Between Indian Pass and Picacho State Recreation Area crystalline basement is overlain by early Miocene (~23 Ma) volcanic rocks. These units are in turn unconformably overlain by undated alluvial sedimentary rocks of the...

Scientists From Across the Globe Warn of Drastic Water Shortages

submitted by: ucsandiego
In the Sierra Neveda, snowpack will shrink by 30 to 90 percent by the end of the century. On the other side of the planet, in the Himalayas, about 70 percent of glaciers are set to disappear. These changes are both caused by climate change and will lead to dramatic water shortages for hundreds of millions of people across the globe, scientists said during a press conference Wednesday at UC San Diego. http://ucsdnews.ucsd.edu/thisweek/2009/05/11_icemelt.asp

Chemical and Physical Characteristics of Pulverized Tejon Lookout Granite Adjacent to the San Andreas and Garlock Faults: Implications for Earthquake Physics: Matthew Sisk, M.S. Candidate, Department of Geological Sciences, San Diego State University - We present new detailed analysis of pulverized Tejon Lookout granite from sections adjacent to the San Andreas and Garlock faults in southern California. The granite is pulverized in all exposures within about 100 m from both faults....
