摘要
Based on the sedimentation,petroleum system,explorative target zone and structural evolution in Junggar Basin,integrated with the basin-controlling major faulting shape,composite structure and genetic mechanism,this paper discussed structural types of three boundary faults of the northwestern margin,northeastern margin and southern margin of Junggar Basin and analyzed the composite boundary structure system and characteristics in the compresso-shear overlay basin.Finally,the paper also interpreted comprehensively the three composite boundary structures of boundary-controlled faults in Junggar Basin.
