| Abstract: | Ductile shear zone and ductile faults have been found in Sanfang district in northern Guangxi, of which the component rocks are mylonitized granite, initial granitic mylonite, granitic mylonite and phyllonite. The structural indicator granitic mylonite shows that its movement direction is of obducted nappe feature. The main deformation time of these shear zones probably was Caledonian period. |
