CONTROLLING FACTORS OF THE METALLOGENETIC TIME-SPACE DISTRIBUTION OF THE ORE DEPOSITS IN SOUTHEASTERN CHINA COAST

There is a distinct zonation in space and an obvious migration in time in the southeastern China coastal metallogenic belt. Thetime-space distribution and mineralization evolution are controlled evidently by the regional Mesozoic tectonic setting and stress field, themagmatism characteristics and the ore potentiality of regional sedimentary metamorphic strata. The magmatic-mesothermal W, Sn andpolymetallic ore deposits outcropped mainly in the eastem Guangdong, the south metallogenic belt; the subvolcanic-hydrothermal porphyryCu - Mo ore deposits in eastern Fujian, the middle belt, the volcanic-epithermal Ag - Pb - Zn ore deposits in eastern Zhejiang, the northbelt. The metallogenetic evolutions are bound to follow the tectonic-magmatic evolution. And the metallogenetic epoches are successivelyfrom south to north in the region.
