During the Early Middle Jurassic, it was in an extensional tectonic environment and formed a series of minor-scale fault basin group, which was distributed in the south of Qilian Mountain and nearby the southern Altyn fault. During the Late Jurassic and cretaceous, it was in the compressional tectonic setting and formed the down-warped basin, which was controlled by the overthrust tectonic regime in the front of Qilian Mountain, the deposition scope was obviously widening.Read More
