Seismic Anisotropy in the Julian Schist, San Diego CA: Robert Gallardo, B.S. Candidate, Department of Geological Sciences, San Diego State University - P-wave velocity measurements of a Julian Schist rock sample collected in the Laguna Mountains region of East San Diego County show significant P-wave velocity anisotropy at near surface conditions. Multiple P-wave velocity measurements were taken from orthorhombic cut sample of Julian Schist using the Tico Ultrasonic Instrument with varying...

Possible relationship of the Iron Mountain metavolcanic assemblage to the El Cajon Mtn ring complex, San Diego Country, California: Justin Kerl, B.S. Candidate, Department of Geological Sciences, San Diego State University - The Cretaceous Santiago Peak Volcanics are exposed along the western edge of the Peninsular Ranges batholith(PRB) and are interpreted as the volcanic cover of the batholitic intrusions. Ring dikes are also a common feature in the western PRB and were first described...

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...
