论福建省闽中裂谷带成矿系统

闽中裂谷带有一套与裂谷构造演化密切相关的矿床组合。裂谷演化的各阶段都伴随着特定的成矿作用，形成了相应的矿床类型。裂谷张开和大洋形成阶段形成层控型块状硫化物矿床；裂谷闭合碰撞阶段形成韧性剪切带型金矿；后裂谷阶段形成岩浆热液矿床。各类（ 式） 矿床的形成常是构造演化各阶段伴随的多种成矿作用叠加和改造的产物，表现为成矿的多阶段和物质的多来源。因此，将裂谷构造环境及其演化各阶段成矿作用和各类（ 式） 矿床作为一个整体，称之谓闽中裂谷带成矿系统

ON THE METALLOGENIC SYSTEM OF CENTRAL FUJIAN RIFT

A set of ore deposit association is developed in the central Fujian rift. Each epoch of the rift evolution is accompanied by certain metallogenesis. The massive sulphide deposits of strata-bound type were resulted from volcanic-exhalative sedimentary process during the opening of rift and formation of ocean (Jinning Movement). The gold deposits related to ductile shear zone were resulted from metamorphism and ductile shearing during the closure and collision of rift (Caledonian). The hydrothermal ore deposits related to volcanics or magmatic rocks were formed during the post-rifting epoch. (Hercynian or Yanshannian). The formation of ore deposit is the result of superimposition and reformation of several metallogenic process. Consequently, the evolution of rift and the unique association of ore deposits are defined as the metallogenic system of central Fujian rift.
