| Comprehensive Deep Profiling of Tibetan Plateau in the INDEPTH Project |
| International Deep Profiling of the Himalayas and Tibetan Plateau(INDEPTH) began in 1992 and finished Ⅰ,Ⅱ and Ⅲ phases in 1992～1994,1995～1996 and 1998～2000 respectively.As a result,crust structures and deep structures of the Himalayas and central Tibetan Plateau were detected,and lots of important papers were published in frontier international journals,which attracted wide attention in the international society of earth sciences.During the fourth phase of INDEPTH,i.e.,INDEPTH-IV,field investigations were conducted, and the focuses,methods and instruments for deep profiling were gradually determined in 2003～2006.Scientists of INDEPTH-IV from Stanford and Cornell Universities of USA,GFZ of Germany,Cambridge University of UK and Chinese Academy of Geological Sciences jointly completed the field work of 100 km deep seismic reflection and 300 km wide-angle reflection and the deployment of 59 broad-band seismographs from May 17 to July 15,2007,thus collecting high quality data of seismic reflections across East Kunlun Mountains and Qaidam basin.The Chinese group of INDEPTH-IV discovered large-scale south Kunlun thrusting and geological evidence for uplift of the Tibetan Plateau in Late Oligocene? Early Miocene period.Project INDEPTH-IV will collect seismographic and broad-band seismic data in northern Tibetan Plateau,deploy MT profiling across the Kunlun Mountains,and conduct geological survey along seismic profiles and data processing of seismic reflections in 2008.Data processing and comprehensive interpretation of deep profiling are to be further arranged in 2009～2010 for revealing crustal structures and deep processes and developing geodynamics of the Tibetan Plateau. |
