INDEPTH (International Deep Profiling of Tibet and the Himalaya), Stanford and Chinese Academy of Geological Sciences

Project INDEPTH (International Deep Profiling of Tibet and the Himalaya) is a multidisciplinary geophysical and geological investigation of the Himalayas and Tibet. Field projects associated with INDEPTH I, II, and III took place between 1992-2000 and covered Southern to Central Tibet. INDEPTH IV’s field season began in May/June 2007 with the acquisition of an active source seismic profile in NE Tibet.

Previous seismic studies have significantly elucidated the response of Asia to the impact of the Indian subcontinent from Southern to Central Tibet. The INDEPTH (International Deep Profiling of Tibet and the Himalaya) IV transect across the northeast boundary of Tibet completes a profile across the entire Tibetan plateau and is expected to clarify the subduction of Asian continental crust beneath the Tibetan Plateau along its northern margin and to probe the geometry and depth extent of the Kunlun Fault.

The collision of the Indian and Asian plates over the past ~55 Ma created the Himalaya and uplifted the Tibetan Plateau. During convergence both plates experienced significant deformation and crustal thickening. Debate continues regarding how Asia has responded to the embedding of the Indian subcontinent with theories including indentor tectonics leading to terrane escape along lithospheric strike-slip faults and lower-crustal ductile flow.

INDEPTH IV incorporates a wide variety of geophysical data. Our field studies commenced in summer 2007 with the acquisition of a 270 km, high-resolution controlled-source seismic profile across the Kunlun suture and the deployment of broadband seismometers across the Kunlun and Jinsha sutures for eighteen months recording. Magnetotellurics and geological mapping in 2008 will complement the seismic acquisition.

Chinese institutions involved in the multinational collaboration include the Chinese Academy of Geological Sciences (CAGS), Chengdu University of Technology, and China University of Geosciences. North American and European institutions include Cornell University, Stanford University, GeoForschungsZentrum Potsdam, Missouri, New Mexico State University, Cambridge, Alberta, Dublin Institute for Advanced Studies, University of Kiel, and University of Haifa.

Biographical Information
I attended Cambridge University as an undergraduate; took my PhD at Cornell University within the Consortium for Continental Reflection profiling (COCORP) then returned to Cambridge to work with the British Institutions Reflection Profiling Syndicate (BIRPS), latterly as a Royal Society Research Fellow. In 1990 I joined Stanford University, where I continue research into crustal structure and evolution.

Research
I study the growth, tectonic evolution, and deformation of the continents (see my Google Scholar profile).
