New timing of the Indosinian intracontinental deformation from the Triassic growth strata in the Kuqa Depression,Southern Tianshan,China

摘要

1.Objectives In the Indosinian duration,series of Gondwana-related plates pieced together and formed the geological sketch of China for the first time,i.e.the Yangtze,Sino Korean,Tarim plates,and other sub-plates that had been isolated for a long time.Subduction and collision among the Tarim,Qaidam,and Qiangtang blocks in Triassic,as well as the closure of the Paleo-Tethys Ocean,reactivated Late Paleozoic suture zones in the Tianshan orogen region(Hendrix MS et al.,1992).
