Abstract: Above 60% oil/gas traps whose formation mainly has close relationship to faulting are developed concentratedly within the fault zone of the Tarim Basin.Faulting of different systems controls the types of oil/gas traps.Thrust decollement mainly results in stacking imbricate,fault bending,fault spreading and fault sliding folds,back thrusting in back thrusting blocks,back thrusting anticlines and tractive traps,and strike slip displacement in efflorescent and en echelon folds.They have become the important targets for the oil/gas exploration of the basin.
