International Field Excursion and Workshop on Tectonic Evolution and Crustal Structure of the Paleozoic Chinese Tianshan
Résumé
The Institute of Geology and Geophysics of the Chinese Academy of Sciences, in Beijing, together with the Xinjiang 305 Project, in cooperation with International Lithosphere Program (ILP) CC-1/4 Projects TOPOCENTRAL- ASIA, ERAS, Chinese National 973 project and Paleo-environment research of NW China, will organize a 7-day (Sept. 10 to 16) international geological transect across the Eastern Tianshan in China, followed by a 2-day workshop* in Urumqi (Sept. 17 and 18). Integrating previous and recent field observations and laboratory analyses, the purpose of this meeting is to recognize collectively key tectonic zones, their geometric and kinematic relationships, in order to reach a common understanding on the Paleozoic evolution of the Tianshan belt and to establish the up-dated model of continental accretion of Central Asia. For practical reasons, the field trip will be limited to 25 participants, but the workshop will be open to any interested participants. The field trip will be 7-day field observations of the key tectonic zones across the Northern, Central and Southern Tianshan. Field–based discussions of the Tianshan Belt will help to place the geodynamic evolution of this range within the general frame of Central Asian geology. The following workshop will provide the opportunity for the international geological community to present new research results in the fields of Earth Sciences (stratigraphy, petrology, structural geology, geochemistry, geochronology, ore deposits, paleomagnetism, seismology, etc... dealing with the geological evolution of Central Asia and related areas). This meeting may provide the opportunity for elaborated syntheses on up-dated understanding of the Paleozoic evolution of the Central Asian Orogenic Belts, and also be a suitable place to set seeds for future international cooperation.
