Session 1: Quo Vadis? Critical unexplored regions of Earth Co-Conveners: BROWN, Larry (Cornell University, USA), DONG Shuwen (SinoProbe Lab. and Nanjing University, China), ZHU Rixiang (Institute of Geology and Geophysics, CAS, China), ASSUMPCAO Marcelo (University of São Paulo, Brazil), EBINGER Cindy(Tulane University, USA), THYBO Hans (ILP), HOU Zengqian (SinoProbe Lab., China), DURRHEIM Raymond (University of the Witwatersrand, South Africa) Quo Vadis (trans. “Where are we going?”) Description: The Earth CT international cooperation program originates from initial discussions during the International Symposium, DEEP-2018. Deep Earth processes control geological evolution, including the formation of natural resources, natural disasters, and large-scale environmental changes at the surface of the Earth. The Earth CT program aims to globally construct long profiles in wide corridors to image the lithosphere by integrative interpretation of geoscientific data. This session welcomes researchers from all over the world to share their research achievements in the field of deep lithospheric studies using integrative techniques including deep seismic reflection and refraction profiling, broadband seismic observations, magnetotelluric sounding (MT) and so on. The aims of the CT program are to reveal the deep structure of the lithosphere, recognize the deep processes of plate movement and their control and influence on the surface system, explore energy and mineral resources at depth, and provide insight into geoscience frontier issues, such as the mechanisms controlling natural disasters and their intrinsic dynamics. Informed by such studies of existing results, we also seek to stimulate future lithospheric research by a discussion of critical tectonic zones that have not yet been probed by modern deep exploration techniques. We hope that this discussion will facilitate new initiatives such as the global deep exploration cooperation (Earth CT) program.
