| Abstract: | Gezhen fault is a most important gold mineralization zone in western Hainan. Deformed quartz is widely developed in tectonite and gold ore. Three-dimension strain analysis of the quartz grains indicates that mylonite type gold deposit, related to the ductile detachment in Indosinian period, is formed in extensional setting, and Jiaojiang type gold deposit related to ductile to-brittle thrust in Later Indosinian to Early Yanshanian period, is formed in pressure setting, and quartz vein type gold deposit related to brittle simple shear and block faulting during Middle to Later Yanshanian period, is formed in transitional shearing state. |
