Mesozoic-Cenozoic exhumation history of Eastern Tian Shan and its geodynamic:insight from DAFT and AFT data
The Tian Shan orogenic belt is a natural laboratory for studying the intracontinental orogeny within the the Central Asian Orogenic Belt(CAOB),which can be divided into the eastern Tian Shan(ETS)and western Tian Shan(WTS).It was formed after the closure of the Palaeo-Asian Ocean and modified by recurrent episodes of Mesozoic-Cenozoic intracontinental deformation[1-3].However,there are remarkable differences between the ETS and WST in the orogenic processes and dynamic background.During the late period,the ETS branched out two high ranges,the Harlik(up to 4600 m)(HR)to the south and Moqinwula(MR)(up to 3900 m)to the north.The two branches also divided three Mesozoic-Cenozoic basins,which are Turpan-Hami(T-HB),Barkol(BB)and Santanghu basin(SB)from the south to north.Although some studies highlight the uplift history of the mountains[4,5],relatively little is known about the origin of uplifts,which limited our knowledge on how this basin-range landscape established and its implications for evolution of the CAOB.
