Session 5: Cratons and their margins Co-Conveners: YUAN Huaiyu (Geological Survey of Western Australia, Perth, Australia), GESSNER Klaus (Geological Survey of Western Australia, Perth, Australia), ZHANG Shuanhong (SinoProbe Lab. and Institute of Geomechanics, CAGS, China), and LEVIN Vadim (Center for Earthquake Research and Information, University of Memphis, Memphis, USA) Description: The interior of continents, especially the stable Precambrian cratons and their margins, preserve a rich tectonic record detailing the formation, reworking, and potential destruction of continental crust and lithosphere. Recent advances in geophysical imaging have provided novel insights into the tectonic history and evolutionary trajectories of Precambrian cratons. In this session, we invite contributions from studies utilizing passive-source, active-source seismic, and other geophysical techniques, emphasizing research into the structural evolution and compositional properties of these ancient continental cores.
