T54A:
Mountain Building in Collisional and Cordilleran Orogenic Systems II


Submit an Abstract to this Session


Session ID#: 57170

Session Description:
Major global mountain belts are fundamentally linked to convergent plate margin processes. Though new multidisciplinary datasets continue to improve spatial and temporal reconstructions of orogenic systems, determining the geodynamic mechanisms influencing mountain building remains an outstanding challenge in tectonics. Orogenesis has traditionally been divided into end-member collisional or cordilleran styles based on convergent margin type. However, ongoing research reveals significant internal variability within collision and subduction zones, as well as important similarities in the structure and evolution of collisional and cordilleran orogenic systems.

This session seeks to bring together geological, geophysical, and geodynamic research from diverse orogenic environments to improve spatiotemporal models of convergent margin mountain building. We invite contributions from seismology, geodesy, geodynamic modeling, geo- and thermochronology, geochemistry, sedimentology, geomorphology, and structural geology that investigate orogenic structure, evolution, and potential driving mechanisms. We particularly encourage studies that combine multidisciplinary datasets, or compare datasets from collisional and cordilleran mountain belts.
