Abstract:

Permo-Carboniferous was the main period ih the late evolution of craton basin for Tarim Plate.its prototype basin was formed in the setting of plate convergence.The uplift and development of the plate was controlled by the continent-continent subduction along Hantengri-Kumux fault in the north side of the plate,leading to the foreland flexural-break subsidence on the north margin;by the oceanic-continent subduction along Kangxi-war fault in the south side,leading to the foreland flexural subsidence of back-arc in Southwest Tarim;by thermal decay and isostatic subsidence of the shriveling stage in Awati-Mangjiar region,Northeast Tarim;and by the mosaic and compression of Beishan-Altun landmass along Qiemo-Xingxingxia fault.During Permo-Carboniferous,tectonic evolution associated with sea level variation(from transgression to regression)and the cli-mate changes (from dry to wet,and then dry again) controlled the sedimentary environ-ment and assemblage pattern of the Tarim Plate.
