Cenozoic structural deformation of the thrusting zone and its control on hydrocarbon accumulation in northeastern Pamir
Abstract：Based on geological survey and recently acquired high-resolution seismic profiles, this paper mainly analyzes the structural characteristics of the Cenozoic thrusting belt in NE Pamir, and suggests the detachments of the Wupor fault which is the forward fault of NE Pamir thrusting belt for different regions. The outcrops and seismic characteristics showed that the Wupor fault slipped along the gypsum-mudstone layer inside the Paleocene strata in the west- ern Bozitag. However, it slipped along both the upper Cretaceous marl and the Paleocene gyp- sum-mudstone in the eastern Bozitag. There was a blind thrusting system in the lower part and a Quaternary piggy-back basin in the upper part controlled by the Wupor fault. The results in- dicate that the Cenozoic deformation of NE Pamir thrusting belt might have began in the late Miocene-early Pliocene and lasted to present. It also controlled the accumulation of hydrocar- bon in this area.
