Paleodepth reconstruction through the Pennsylvanian Finis Shale of Texas: Insights from brachiopod oxygen isotopes Leah Carrigan ABSTRACT The Upper Pennsylvanian Finis Shale occurs within the Graham Formation of the Cisco Group and represents a mud-dominated environment along the eastern shelves of the sub-equatorial Midland Basin (Pierce et al., 2010). In a representative section of the Finis Shale, Forcino et al. (2010) documented a fundamental decrease in the abundance and biomass...

The West Bullion-Mesquite Lake Fault Step-Over: Assessment and Comparison With Faults of the Eastern California Shear Zone, Twenty-Nine Palms Marine Corps Base, California Kaitlin Wessel ABSTRACT Twenty-nine Palms Marine Corps Base is positioned in a step-over region between the West Bullion Fault and Mesquite Lake Fault. Both of these belong to a series of transform faults located in the Mojave Desert called the Eastern California Shear Zone (ECSZ) that trends northwest to southeast....

Enigmatic new Osagean unit sitting atop Lower Mississippian Joana Limestone at Granite Mountain Island, Middle Range, West-Central Utah Luke A. Ranieri ABSTRACT The enigmatic Middle Range (MR) unit that unconformably overlies the Joana Limestone in the Middle Range, Utah, was deposited on the eroded surface of the Joana bank of the Antler forebulge in the Lower Mississippian in warm, tropical sea water, and fits the classification of a Waulsortian or Waulsortian-like mudmound due to...

Saprock: A long term recorder of ground shaking, Peninsular Ranges, southern California Marck Maroun ABSTRACT Saprolization is commonly viewed as an isovolumetric process. However, it has not been studied extensively in seismogenic areas. Hence, we undertook a detailed study of five sites located at disparate distances to the seismically active Elsinore fault. Data obtained during this study along with the results of earlier investigation of five additional sites, support the idea of...

Fault zone architecture of the San Jacinto fault zone in Horse Canyon, southern California: implications for focused fluid flow during rupture at shallow crustal levels Nissa Morton M.S. Candidate Advisor Dr. Gary Girty ABSTRACT Stream cuts in Horse Canyon southwest of Anza, CA have exposed the fault core, adjacent damage zone, and wall rocks of the San Jacinto fault at an approximate depth of 0.4 km. Here the juxtaposition of tonalitic plutons provides a unique opportunity to assess...

Toward Development of a Long Rupture History of the Northern Imperial Fault in Mesquite Basin, Imperial Valley, Southern California Rebecca Tsang M.S. Candidate Advisor Dr. Thomas Rockwell ABSTRACT The Imperial fault is a 70-km long, northwest-striking, dextral fault located in the Salton Trough, which along with the San Jacinto and Elsinore faults, are considered part of the San Andreas fault system and accommodate a significant proportion of the North American-Pacific plate-boundary...

Estimation of Lateral Variations of the Mohorovičić Discontinuity Using 2D Modeling of Receiver Functions Rumi Takedatsu Advisor Dr. Kim Bak Olsen ABSTRACT We have used 2D finite difference modeling to examine the efficacy of estimating a relatively abrupt offset (>~35o) in Moho depth with a slant-stacking technique (Zhu and Kanamori 2000) from radial 0-2Hz P-wave receiver functions (RFs) at a single or a few closely-spaced stations. In particular, we have examined the advantage...

Timing And Style Of Miocene Deformation, Indian Pass And Picacho State Recreation Area, SE California, U.S.A. Krista Muela Advisor Dr. Gary Girty ABSTRACT The Chocolate Mountains anticlinorium is a complex structure extending from the San Andreas fault on the west to south-central Arizona on the east. It is well exposed between Indian Pass and Picacho State Recreation Area, SE California, where Neogene rocks reveal a complex record of Paleogene to early Miocene extension followed by...
