Geological outline of the Tianshan Mountains is described along the Dushanzi-Kuqa Highway, Xinjiang-Uygur Automonous Region, west China. The area is mainly occupied by Paleozoic sediments. On the basis of the lithology of the sediments and left-lateral shear zones, the area is divided into three belts : Erenhabirga-Borohoro-Yining, Narat-Erbeng-Harke, and Tarim belts from north to south. The Erenhabirga-Borohoro-Yining Belt is characterized by intermediate to felsic volcaniclastic rocks of Devonian to Carboniferous time, and has an affinity of continental arc or island arc. The Erenhabirga-Borohoro-Yining Belt is bounded from the Narat-Erbeng-Harke Belt by an E-trending, sinistral mega shear zone : the Narat Mountain shear zone. The Narat-Erbeng-Harke Belt has an affinity of carbonate shelf, and mainly comprises Silurian to Carboniferous limestone sequence with mafic volcanic layers in Lower Devonian horizon. The Narat-Erbeng-Harke Belt is bounded from the Tarim Belt by the Tarim northern margin shear zone. The Tarim Belt is characterized by Devonian red sandstone showing a continental 'depositional environment. We interpret that these three belts, formed under different Paleozoic sedimentary environments, were tectonically rearranged by huge sinistral strike-slip faults at the end of Paleozoic time.
