Their focal mechanism solutions show that the nearly E-W or WNW-ESE horizontal tensional stress controls the lithospheric stress field in the region.
震源机制结果显示，近E-W向或WNW-ESE向的水平扩张应力控制着该区的岩石圈应力场；

Pingcha gold deposit is a Sb-Au of rich in sulphide, controlled by the E-W secondary fracture and alteration zone and being small in scal but high in grade.
