摘要
HUATSHABA矿床位于著名的中非刚果(金)铜钴矿带上,主要产于罗安群矿山组(R2)地层中;成矿硫元素来源于海水;围岩的形成在新元古代,低温海相环境,并有细菌参与;矿床的形成经历了一个大型而广泛的热液系统;矿床的形成分为早期成岩成矿阶段、成岩期成矿阶段、晚期成矿阶段和造山成矿作用、表生氧化阶段四个成矿阶段;综上,矿床为典型的沉积型铜钴矿床。
The Huatshaba Cu-Co deposit lies in the famous Central Africa-Congo(Kinshasa)Cu-Co ore belt and occurs in the Mine Formation(R2)of the Roan Subgroup.Sulphur was derived from seawater,wallrock was formed in the Neoproterozoic low-temperature marine environment with bacteria involved.The ore-forming process may be divided into 4 stages such as early diagenetic stage,diagenetic stage,late diagenetic and syn-to post-orogenic stage and supergene enrichment stage.This deposit is a typical sedimentary Cu-Co one.
