【Abstract】 Bikou ductile shear zone distributing along Kangxian county-Nianba-Maziba developed in the Devonian System and the upper Guanjiagou Formation of Sinian System. The Ductile shear zone Showed that strong thrust-nappe orogenic movement in Hercynides period,and strong NNW pres-stress in Indosinian Period;It formed a series of thrust-nappe structures in the area, and established the structural framework of the area.更多还原
