Geology professor to give virtual talk on dehydration in subduction zone
Dr. Besim Dragovic, who is an assistant professor at the University of South Carolina, will give a virtual talk, “Pulsed Metamorphism and Fluid Release at the Subduction Interface,” on Tuesday, Oct. 13, from 1 to 2 p.m.
The talk can be accessed online through a Zoom link.
Dehydration during subduction zone metamorphism plays an important role in Earth's volatile budget. The transport and subsequent release of fluids during metamorphism of the down going oceanic lithosphere can have a strong influence on many geologic processes, including arc volcanism, intra-slab earthquakes, large-scale element recycling, and ore genesis.
The timescales of fluid release may be short, ranging from tens to hundreds of thousands of years for metamorphic dehydration reactions to less than a year for the transient passage of the resultant fluids.
In his talk, Dr. Dragovic will present results from radiogenic and stable isotope geochemistry, petrology and geodynamic modeling to elucidate the nature and timescales of fluid release at the subduction interface using field-based examples from the Greece, the Western Alps, and the Western U.S. He was invited to give the talk by Department of Geology and Environmental Sciences Assistant Professor Wentao Cao.
