The Tarim Basin records the history of deposition and deformation affected by the Indian—Eurasia collision during the Cenozoic. The seismic data shows that the faulted rigid Bachu uplift, central Tarim, is a paleo-uplift covered by Quaternary deposits. NW-striking Aqia fault, Qiaolaimaiti fault and Salambulake syncline and anticline between them were developed on the north margin of the Bachu uplift, northward adjacent to Awati depression. Many seismic lines and well data show that the Aqia fault is a deep basement-involved,  south-dipping thrust fault,  and the shallow structures are both Qiaolaimaiti north-dipping thrust fault and Salambulake fold.
