The fault controlled the magmatism and metallization relevant to the contact zone, and deformed successively and produced cataclastic rocks and two sets of joints ; the second stage was from late cretaceous to eocene. the fault zone deformed right - laterally under ne - sw striking transtention, and new joints zone was produced at the end of the two main faults because of local stress concentration. the fault produced inchoative cataclastic rocks, and two sets of typical joints in plutons ; the third stage of deformation was relatively faint and only a little of microcracks was produced and infilled with vei ns in the deformed rocks, which was during the himalayan movement

The cataclastic rocks appeared in the fault zone include structural lenticles, fault breccias, protocataclasite and cataclasite. the microscopical cataclastic deformation mechanisms involved are microcracking, frictional sliding and pressure - solution, but there might have had ductile deformation relating to dislocation sliding in feldspar and quartz of the plutons
