Abstract: Hongqikan region is located in the thrust tectonic belt in Piedmont of northern of Turpan–Hami Basin. By the
NW—SE compressive stress，the Jurassic mainly developed into the SW—NE master fault and the NE—SE or near the northsouth
secondary fault vertical or oblique to the master. In the master fault，thrust stacked successively from north to south，
forming a unique fracture combination of imbricate and fracture distribution characteristic of plane parallel of a“River”shape.
From west to east，Hongqikan belt shows three sections of dual thrust imbricate tectonic features that is imbricate thrustimbricate
stacking-imbricate thrust. The late Jurassic sediments is the major development stages for imbricate thrust，and the
thrust tectonics play a very important role in dual thrust imbricate structure development of Hongqikan in Cretaceous，which
stereotyped is later by the large angle thrusting movement transformation in Himalayan.
