湘西北下寒武统黑色岩系中的钒矿床

V deposit in Lower Cambrian black rock series of Northwestern Hunan

湘西北下寒武统木昌组黑色岩系,是一套富含有机质的硅、磷、碳岩石建造,富集多种有色金属及贵金属等元素,其中以黑色岩系型钒矿资源最为丰富。矿床与黑色岩系有着极为密切的关系,二者不仅具有同源性,而且均在富微生物和营养物质的缺氧环境中蕴聚。矿床具有微生物成矿与热水沉积的双重特征,成因属生物地球化学矿床范畴。

The Muchang Formation black rock series of Lower Cambrian in northwestern Hunan is a set of Si, P, C rock structure containing rich organic matters with kinds of nonferrous metals and noble metals elements enriched, of which the V mineral resources in black rock series is the most abundant. The deposit has a close relationship with the black rock series because of the same origin and characteristic that they will be both assembled in hypoxia but rich animalcule and nutrient matters condition. The deposit has owned double characteristics of animalcule metallogeny and hydrothermal sediment with the genesis belonging to the scale of biological geochemical deposit.
