Session 3: Deep structure and evolution of Eurasia Co-Conveners: XIAO Wenjiao (Xinjiang Institute of Ecology and Geography, CAS, China), SCHULMANN Karel (Czech Geological Survey), ZHAO Liang (Institute of Geology and Geophysics, CAS, China), MOONEY, Walter D. (U.S. Geological Survey, USA), CARBONELL Ramon (CSIC-Inst. Earth Sciences, Spain), CHEN Xuanhua (SinoProbe Lab., China) Description: Eurasia is the largest and most geologically diverse land mass on Earth, composed of several representative orogens including the Altaids, Caledonides, Hercynides, Tethysides and Uralides. More than five decades of exploration has probed their deep structure, including a variety of geologic, geochemical and geophysical methods, including active and passive seismic studies as well as non-seismic methods. This session welcomes contributions that report new insights into the deep structure of Eurasian orogens. Results that are multi-disciplinary and that combine multiple data sets are welcomed.
