Title: Tectonic Evolution and Hydrocarbon Potential in Heshituoluogai Basin in Northern Margin of Xinjiang
Abstract:According to the comparison and correction between latest and old seismic data,this paper presents the whole structural interpretation and evolution of Heshituoluogai basin using basin analysis theory...According to the comparison and correction between latest and old seismic data,this paper presents the whole structural interpretation and evolution of Heshituoluogai basin using basin analysis theory,basin-mountain coupling idea and balanced cross section technique.it is concluded that: 1) Heshituoluogai basin originated from the collision and dip offset among Siberia plate,Kazakhstan micro-plate and Junggar micro-plate is a secondary compresso-shear basin situated on the hanging wall of major thrust belt;2) the evolution of Heshituoluogai basin is subject to Junggar terrain,the double tectonic activities of its basement should be earlier than Late Triassic before which it was connected with Junggar basin as a boundary of it,and 3) the basin cover development can be divided into 4 stages: initial development stage(T3--J1b),quick deposition stage(J1s-J2t),whole subsidence stage(K) and boundary faulting revival stage(E-Q),of which Jurassic is the main basin-formed period associated with largest structural deformation.Read More
