Sierra Drips CD Project page

What:

Removal of mantle lithosphere has become a popular hypothesis for many orogens, from the Appalachians to the Tibetan Plateau and from the Archean formation of lithosphere to ongoing tectonism in the Andean arc. The physical process remains poorly observed. The earlier Southern Sierra Continental Dynamics Project and Sierran Paradox CD Project have led to the suggestion that the Sierra lost mantle lithosphere under its southern part by about 3 Ma. This relatively young event occured at a transform boundary and thus lacks complications present in places like the Andes. This project and its companion EarthScope project (SNEP) seek to define the lithospheric structure and geological history of the Sierra and from that learn the importance of this foundering in California tectonics, the physical parameters controlling foundering, and the mechanism of foundering. This information should provide a better understanding of the physics of this process in general and allow for more careful application of this process as an explanation in other orogens.

Project personnel will be examining:

• the history of uplift and subsidence through geomorphology, low-temperature geochronology, and stratigraphy along the range
• seismotectonics of modern deformation
• the electrical structure of the lithosphere and asthenosphere under the region and its connection to seismic constraints
• changes in space and time in the mantle through xenoliths
• constraints on the evolution of the lithosphere along the Sierra through volcanic petrology and geochemistry
• the original production of high-density eclogitic rocks along the Mesozoic Sierran arc through petrologic models and geochemical observations
• geodynamics of mantle foundering through numerical experiments and the implications for volcanism, tectonism, and causes of foundering
• in the related SNEP group, work will define the seismological characteristics of the Sierran crust and mantle, ideally identifying variations in composition, temperature, strain history, and presence of volatiles
