摘要
New structural studies and 2D and 3D seismic profiles reveal that in the Upper Paleozoic-Mesozoic in the western Junggar Basin develop Dalabute strike-slip fault and Karamay-Xiazijie fault belt.The former assumes normal flower-shaped structures, the latter develops right strike-slip structures which form an echelon arrangement of Wuerhe anticline, Xiazijie anticline, high angle-dipping shear faults. In Late Paleozoic-Mesozoic the northwestern margin of Junggar Basin occurred strike-slip movement dominated by right shear and overthrust structures, shaping the strike-slip faults and shear fault dogleg folds. This could deny the previous long-time idea of that in the northwestern margin of Junggar Basin developed overthrust nappe structure.
