| 摘 要： | 研究表明，湖南雪峰地区存在前地槽构造层，该区金矿的成矿物质主要来自赋矿地层，成矿流体主要为大气降水，其主成矿期为加里东期、印支－燕山期。金的成矿作用与壳体的演化关系密切，前地槽阶段为矿源层的形成提供了物质基础，地槽阶段形成矿源层并发生金成矿作用，地洼阶段金发生改造迭加成矿。

| Abstract: | It is revealed
that there exists the pre-geosynclinal formation in the Xuefeng district. The gold
deposits in this area mainly formed in Caledonian and Indo-C hinese-Yanshanian periods,
its ore-forming materials are derived from the ore -hosting strata, and its ore-forming
fluid mainly originates from the meteoric water. It is proposed that gold mineralization
is closely associated with the c rustobody evolution, i. e., the pre-geosynclinal stage
prepared materials for t he formation of gold source bed, the source bed formation and
gold mineralizatio n took place during the geosynclinal stage, and gold reworking and
superposition happened in the diwa stage. |
