T12A:
Deep Structure and Geodynamics of the Continental Convergence Zones II


Submit an Abstract to this Session


Session ID#: 57158

Session Description:
Old continents have thick lithospheres, complex deep structures and compositional variation, that in turn produce even more complexity during continental collision. Continental geodynamics is becoming evermore important in the understanding of continental formation and evolution. For example, ancient continental convergent boundaries are related to the formation of major intracontinental oil and gas bearing basins in the cratons, while active continental convergent zones modify Earth’s climate. Hence the decoding of deep structure, composition and geodynamics of continental convergent boundaries is an important subject for geologists, geophysicists, and geochemists. We welcome submissions on all aspects of global continental convergent boundaries, ancient and modern.
