湘西北下寒武统黑色岩系中贵金属镍-钼-钒矿床的有机成矿作用

Organic metallogeny of the precious metals Ni-Mo-V deposit in black rock series of Lower Cambrian,Northwestern Hunan

湖南西北部广泛分布的下寒武统木昌组黑色岩系中富含Ni、Mo、V,多处形成了镍-钼-钒多金属矿床(点)。主要可划分的类含矿岩性序列为:1含磷黑色岩系——镍-钼矿床;2碳硅质黑色岩系——钒矿床。研究认为,有机成矿作用对镍-钼-钒矿床的形成起了主导作用。

The black rock series bearing abundant Ni, Mo, V of the Muchang Formation in Lower Cambrian spread broadly in Northwestern Hunan, where a lot of Ni-Mo-V polymetallic deposits have formed. Two types of rock series bearing the precious metals can be defined as followings.1, the black rock series bearing phosphor, where the Ni-Mo deposit occured 2. the carboniferous silicious black rock series, where the V deposit occured. The research has believed that the organic metallogeny is dominant to the formation of the Ni-Mo-V deposit.
