Arc-Continent Collision Systems: The Rock record, fabric evolution and plate Interactions

Session ID#: 79188

Session Description:
Arc-continent collisions have been important processes in orogenesis throughout geologic time and detailed petrological, structural and geochronological studies have yielded significant advancements in understanding this fundamental tectonic environment. More recently, this knowledge base has been integrated with plate motion reconstructions and studies of mantle dynamics and surface processes, providing a more wholistic view of arc-continent collision processes. Here, we seek oral and poster presentations of integrative studies of modern or ancient arc-continent collisions, particularly in the areas of high-pressure metamorphism, transpression, fabric development, geochronology, and numerical modeling.
