| 摘 要： | 通过分析川西北金矿集中区的地层在金成矿中的作用 ,指出金矿成矿物质是多源的 ,且以寒武系及其下伏地层为主要物源 ;构造 -岩浆活动是地层中成矿物质活化、迁移的主要动力源 ,浅部赋矿地层的物理化学性质是金成矿的关键因素。

| Abstract: | A study of the role of the strata in ore-formation of fine-disseminated gold mineralization in northwest Sichuan indicates that ore material here was polygenic and derived mainly from the Cambrian and its underlying strata.Ore material was remobilized by tectonomagmatic activity.while physical-chemical properties of the host strata was the key factor to ore precipitation. |
