Abstract

The Jiuxi (Western Jiuquan) Basin. located in the west of the Hexi Corridor. NW China. is a foreland basin which has been active since the Early Jurassic. It was formed as a consequence of the progressive northwards migration of the North Qilian thrusts in response to sinistral shearing along the 2.000-km long Aerjin (Altun) Fault. Sedimentary deposits in the basin are controlled not only by foreland loading and thrusting. but also by the development of listric normal fault. at high angles to the thrust belt. At the junctions of these two sets of faults. thick organic-rich sediments and reservoirs have accumulated.
