My name is Jason Ott, and I am a Ph.D. student in the graduate program in the Department of Earth and Space Sciences at the University of Washington studying the deformation and rheology of amphibole minerals in subduction zones. My current research involves mapping the minerals and their orientation in naturally deformed blueschist samples by electron backscatter diffraction (EBSD) and using these maps to try and understand how these rocks are deforming deep in the Earth. Connecting the work on these natural rocks with deformation experiments on glaucophane, the dominant amphibole mineral in many blueschists, will help us better understand the deformation behavior of these rocks in particular and the dynamics of subduction zones as a whole.
Subduction zones are the complex regions where oceanic crust dives into the Earth to be recycled, and are a key element to understanding the plate tectonics of our home planet. Subduction zones host some of the most dangerous hazards on our planet, including megathrust earthquakes, tsunamis, and explosive volcanism-and are often in close proximity to population centers. Therefore, the work we do to better understand them is of importance beyond the scientific community.

The second manuscript from my Master's research: Structural behavior of C2/m tremolite to 40 GPa: A high-pressure single-crystal x-ray diffraction study, has been accepted for publication at American Mineralogist and is now in preparation for press. This work, in collaboration with Quentin Williams (my M.S. advisor), Bora Kalkan, Martin Kunz, Genesis Berlanga, and Ali F. Yuvali, extended well beyond my time as a student at UCSC--thanks to the challenges of doing science during a pandemic! We are excited to finally see this study on the metastability of tremolite, and the implications of its metastability to subduction-zone and planetary science, on its way to publication.
