【摘要】 湘西北镍钼矿床产于寒武系下统木昌组黑色岩系底部的含磷岩性序列中。含矿岩系具有热水沉积和生物化学沉积的地球化学特点。成矿是在有机质 (生物地球化学 )参与下发生的。矿床是微生物成矿和热水沉积双重作用的结果更多还原

【Abstract】 Ni-Mo deposits in northwestern Hunan occur in the P-bearing lithologic sequence at the bottom of Muchang Formation, Lower Cambrian Series. The geochemical characteristics of the ore-bearing rock system show hot-water sedimentary and biochemical sedimentary. The organic matter (biochmistry) has part icipated in the metallogenesis. The ore deposits are formed by the dual origin ofmicrobiomineralization and hot-water sedimentary.更多还原
