Structure, Tectonics, and Earthquake Hazards of Cratons
Session ID#: 158110
Session Description:
Cratons form the “stable” cores of continents. While they are generally resilient to destruction and recycling, recent studies from geophysical imaging, geological surveys, geochronological measurements, and geodynamic modeling provide evidence for significant structural and compositional modifications of the cratonic lithosphere. Tectonic features such as basins, rifts, faults and folds, arches, and domes existing across cratons also require changes in the geodynamic states of the lithosphere “post-cratonizaton”. Abundant intraplate seismicity suggests that some of these structures are active today. Cratons, from their interiors to the margins, provide an ideal setting to address a variety of topics on the dynamics and stability of continental lithosphere, most effectively done through cross-disciplinary collaborations. This AGU session aims to facilitate sharing of new data and results across disciplines to help elucidate the structure, tectonics, earthquake hazards, and evolution of cratons. We invite contributions from multiple disciplines, including but not limited to geology, geophysics, geochemistry, rock physics, geochronology, tectonics, and geodynamics, with a particular interest in studies that cross-disciplinary boundaries and/or cross-temporal and spatial scales.
