Collaborative Research: RUI: Glacier resilience during the Holocene and late Pleistocene in northern California

Global temperature rise since 20 ka and during the last century has caused glaciers to retreat and disappear throughout the world. Some glaciers, however, continue to persist today, and highlight the importance of precipitation on maintaining glaciers in a warming climate. The Trinity Alps Wilderness in the Klamath Mountains, northern California provides evidence for multiple glacial ad...

RUI: Collaborative Research: Early Cenozoic basin development in the southwestern US: a record of extensional collapse following subduction of an oceanic plateau?

Recent tectonic models of the southwestern US Cordillera suggest that a flattening slab, coupled with the subduction of an oceanic plateau (the conjugate Shatsky Rise: CSR) in Late Cretaceous ? Eocene time (90-40 Ma) led to subduction erosion, extension and associated paleogeographic change. This 3-year research project will test the hy...

Late Quaternary slip rate of the western Pinto Mountain Fault, Morongo Valley, CA

Through San Gorgonio Pass, the San Andreas Fault system forms a restraining bend, locking the fault and creating an apparent slip and earthquake deficit in this region (e.g., Matti and Morton, 1993; Yule and Sieh, 2003; Cooke and Dair, 2011). The potential for a major through-going rupture on this portion of the fault hinges upon our understanding of potential pathways for earthquakes. A ?southern? pathway along the...

Collaborative Proposal - High-precision cosmogenic burial and exposure dating (10Be, 26Al, 36Cl) on late Pleistocene fan surfaces to constrain long-term San Andreas fault slip rates

This project is a collaborative proposal between R. Heermance (CSUN) and N. Lifton (Purdue Univ.). Analyses must be performed at PRIME lab where they have developed new, improved analytical techniques that greatly improve the probability of project success. In past SCEC proposals, analytical costs have not been incl...

RUI/Collaborative Research: Plio-Quaternary history of basin evolution, climate change, and fold growth in the Qaidam Basin- investigating wind-enhanced climate-tectonic feedback relationships.

The project aims to document acceleration in fold-growth due to increased wind erosion within the hyperarid western Qaidam Basin, China, and thus would provide the first example of wind-enhanced tectonics on Earth. In addition to understanding climate-tectonic feedbacks, this project will yield multiple hi...
