Blueschists of Syros Island, Greece

Blueschists of Syros Island, Greece

High pressure subduction complexes preserve on Syros Island in Greece record different deformational processes and mechanisms as they transition from subduction to exhumation.

Valle Santo Thomas, Baja California, Mexico

Valle Santo Thomas, Baja California, Mexico

The Agua Blanca and San Miguel-Vallecitos faults in Baja California accommodate ~14% of plate boundary motion at this latitude. We are investigating their rates of slip and kinematic linkages with other faults within the San Andreas system and the Gulf of California Rift Zone.

Mantle xenoliths from the Cima Volcanic Field, California

Mantle xenoliths from the Cima Volcanic Field, California

Xenoliths erupted from young volcanoes in the Mojave region are clues to understanding the present-day rheology of the lithospheric mantle and the nature of the lithosphere-asthenosphere boundary.

Terraces along the Rio Grande River in northern New Mexico constrain incision rates for this steeply incised gorge.

 

Primary Research Activities

Research in my group focuses on the mechanics and kinematics of continental deformation at plate boundaries and spans a wide range of spatial and temporal scales.  We examine the geomorphic expression of young, active faults, and we also study older remnants of deep-seated ductile shear zones exhumed from greater depth within the lithosphere.  My students and I apply a wide range of field, structural, geochronological and analytical methods.  To find out more about some of our active projects, check out the research page.

If you’re a prospective graduate student, please feel free to check out the Student Opportunities page and don’t hesitate to contact Dr. Behr or anyone else in the Research Group if you have questions about the graduate program at UT Austin.

News & Events

The Behr Research Group welcomes two new Ph.D. students!
Welcome to Pamela Speciale and Alissa Kotowski. Pamela will be working on strain localization in mantle rocks via deformation experiments on olivine and Alissa will be working on subduction zone processes as preserved in HP rocks in the Aegean.
Congratulations to Kory Kirchner on finishing his M.S. thesis!
Kory's thesis entitled "Early Miocene subduction in the western Mediterranean: constraints from Rb-Sr multi-mineral isochron dating" is available for download here and will be written up as a publication this fall.
