摘要
湘西北地区下寒武统黑色岩系属于海侵体系域之还原环境的缺氧沉积。镍钼矿床主要产于木昌组底部的含磷岩系中。含矿岩系具有热水沉积和生物化学沉积的地球化学特征。成矿是在有机质(生物地球化学)参与下发生,并有热水沉积的加入。矿床是微生物成矿和热水沉积双重作用的结果。
Black rock series was formed in the anoxic reductive environment in marine system of Lower Cambrian in Northwest Human. The Ni-Mo deposit occurred mainly in the phosphorite sequence at bottom Muchang Formation. The host rocks possessed of hot-water sediment and biochemical geochemical characteristics. Mineralization was took part under the orgin material（biogeoehemistry）, at the same time, the hot-water joined into ore-forming. Ni-Mo deposit forming was the results of microbe hot-water sedimentary.
