Session ID#: 13130

Session Description:
Tectonochemistry is a branch of geochemistry aimed at understanding tectonic processes. The potential breadth of tectonochemistry is wide and includes (but is not limited to) geochemical studies of subduction-, collision-, rift-, and plume-related processes that contribute to a greater understanding the evolution of Plate Tectonics on Earth.

We invite submissions from tectonochemists integrating a variety of geochemical methods and principles in spatial and/or temporal contexts in order to resolve large-scale tectonic questions. We anticipate particular interest from those studying evolution of orogenic and thermo-magmatic systems, timescales of crustal processes, generation and differentiation of the crust. This session will highlight the breadth of activities happening across this fundamental branch of geochemistry.
