Abstract:Through the field geological research, a set of unique tectonic assemblages was found in this area.These structures (S-C planes, lineations, folds, asymmetric structures, etc.) appear in combination in this area. Combined with the analysis and identification in the laboratory, it can be seen that the rock has internal strain structure and nuclear mantle structure.It is further shown that Shuiquangou area is an axial NE-NNE ductile shear zone.The distribution of copper polymetallic ore bodies is related to the axial direction of the ductile shear zone, and a banded distribution occurs.The distribution of the ore bodies is controlled by the secondary structure of the ductile shear zone.The characteristics of mineralization in this area are also related to the strength of ductile deformation to some extent: in the better parts of the mineralization., mineralization from mylonite to weak mylonite and mylonitic mineralization tends to be weakened.
