Tectonics

Research in Tectonics at USC is focused on two areas: 1) the mechanics of crustal and lithospheric deformation and 2) the evolution of magmatic systems. Research ranges in scope from microstructural studies of deformational processes and rheology, to the mechanical and geometrical analysis of the largest-scale tectonic features on our planet.    

We have a particular focus on the tectonics of convergent and transform plate boundaries, including active faulting, arc magmatism, late-orogenic extension, and the exhumation of metamorphic rocks.  Research methods include geodetic studies of active plate boundary deformation, paleoseismology, thermobarometry and geochronology to define pressure-temperature-time paths of rocks, paleomagnetism, and thermo-mechanical modeling.

Current research projects involving graduate students include:

• Active tectonics of intracontinental transforms such as the San Andreas and the North Anatolian fault
• Analysis of crustal strength using microstructural analysis of exhumed rocks in extensional tectonic environments in SE California and southern Spain
• Emplacement of plutons in the Mesozoic arc of California
• Origin of back-arc basin extension in the Western Mediterranean region
