Evaluation of XRD and Raman peak broadening in shock-metamorphosed carbonates from selected carbonate-target bolide impact structures: Kean Bliss, M.S. Candidate, Department of Geological Sciences, San Diego State University - Identification of shock metamorphism in minerals is an important line of evidence for confirming the origin of potential impact-generated structures and associated deposits. Unlike common quartz and feldspar occurring in crystalline target rocks, shock-metamorphosed...

Physical and Chemical Characteristics of Unweathered Pulverized Rock along the San Andreas Fault, Little Rock, CA: Emily Allen, M.S. Candidate, Department of Geological Sciences, San Diego State University - We present new observations on pulverized granitic rocks recovered from a shallow core adjacent to the San Andreas fault near Little Rock Creek. The site is characterized by extensive outcrops of granitic rocks with varying degrees of damage, at distances of up to a few hundreds of...

Biotic Response of Ostracodes to the Middle Eocene Climatic Optimum (MECO; 40.0 Ma) in the Southern Indian Ocean (ODP Site 748): Jared Warner, M.S. Candidate, Department of Geological Sciences, San Diego State University - The long-term cooling trend from “greenhouse” to “icehouse” conditions through the middle-to-late Eocene (49.0 – 33.7 Ma) was interrupted by the middle-Eocene Climatic Optimum (MECO; ~40.0 Ma), a transient (~500 kyr) global warming of ~4-6 C° widely recorded in...

Mytilus californianus as an environmental monitor: a case study from central California: Frank Forcino, M.S. Candidate, Department of Geological Sciences, San Diego State University - Intraskeletal oxygen stable-isotope ratios (δ18O) and minor element ratios (Mg/Ca) were examined in modern Mytilus californianus specimens to test the hypothesis that these variables record ambient seawater temperature, and therefore can be measured in fossil specimens as a means of reconstructing...

Magnetotelluric Investigation of the Santo Domingo Basin, Rio Grande Rift, New Mexico: Peter Winther, M.S. Candidate, Department of Geological Sciences, San Diego State University - Magnetotelluric (MT) investigations of the Santo Domingo Basin were made in 2000-2007 to assess the deep stratigraphy and tectonics of an intra rift basin. The studies were conducted during the SAGE (Summer of Applied Geophysical Experience) program to provide ‘hands-on’ learning experiences for students and...

Latitunal Controls on the Martian Crater Densities: Dylan Collins, B.S. Candidate, Department of Geological Sciences, San Diego State University: In order to gain new insight into Mars’ planetary dynamics, an examination of Martian crater densities as a function of latitude was completed. There are two complete crater catalogs of the Martian surface; one manually compiled by Nadine Barlow and one compiled by crater counting software created by Tomasz Stepinski and colleagues. After loading...
