Abstract: The Jinwozi gold deposit occurred in Hercynian biotite adamellite and Jingwozi Formation (Upper Devonian).Its mineralization type is the quartz-vein one and the altered-rock one.This study reveals that a granitic magma system,and low-angle ductile-brittle fault and high-angle extension-tension shear second order fault system closely a ssociated with the minerlization in terms of space,time and materials,accounts for the gold minerlizaion.The minerlization types are controlled both by the tectonic stress field and the fracture mechanic property.
