摘要
中国东南沿海中生代的矿床在空间上具有明显的分带性,在时间上具有明显的迁移性。研究表明,区域中生代矿床的时空分布和成矿演化明显受着区域构造应力作用方式、岩浆作用特征、赋矿地层和岩石的含矿性特征等因素的制约。
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.
