Dear Colleagues, Apologies for cross-posting. We invite you to submit an abstract to the following session at the GSA 2019 Fall Meeting in Phoenix, Arizona, focused on metamorphism and orogenesis at convergent plate margins. Please note the abstract submission deadline is Tuesday, June 25th, 2019. GSA will be held from September 22-25, 2019, in Phoenix, Arizona. T23. Metamorphism and Orogenesis at Convergent Plate Margins https://community.geosociety.org/gsa2019/learn/technical/topical <https://community.geosociety.org/gsa2019/learn/technical/topical> GSA Structural Geology and Tectonics Division Session Description: Convergent plate margins are locations of intense deformation, metamorphism, and magmatism, where significant heat, fluid, and mass transfer may take place. Quantifying the fluxes and drivers of orogenic processes is critical to understanding the geodynamical evolution of the lithosphere, the rates and mechanisms of metamorphism at elevated pressure and temperature conditions, and for constraining the nature of mountain building and continental growth through geological time. In this session, we seek contributions investigating the drivers and petrological/ tectonic implications of regional or contact metamorphism at convergent plate margins, with emphasis on continental crustal materials. We encourage studies that consider a variety of techniques, such as field mapping, petrological phase equilibrium modeling, petrochronology, geochemistry, and geodynamic and/or geophysical modelling, and studies that span a wide range of spatial and temporal scales.
