摘　　要：通过对南平巨口钼矿床控矿地质条件分析,认为北东向的政和-大埔断裂带和南北向浦城-嵩口断裂带复合交会部位控制了成矿小岩体群,强调了南北向构造迭加为成矿母岩侵位提供了通道和赋存空间,同时其次级断裂构造控制矿体的分布产状及规模;控矿母岩-黑云母花岗岩,高硅、高碱、高钾,低钙、镁对成钼有利。文章总结矿(体)床特征,分析围岩蚀变,提出了区带找矿方向和找矿标志。By the analysis of the metallogenic conditions of the molybdenum deposit,in this paper,it is suggested that the converqence and intersection region of the ne-trending Zhenghe-Dapu fallt and the ns-trending Pucheng-Songkou fault,has control over the clusters composed of small rock mass related mineralization,and emphasized that the overlaps of the ns-trending structures provides the place of the channel and ocurrence for the invasion of the bed rock related mineralization,moreover their secondary fault structures confine distribution,occurrence and scale of the molybdenum orebodies;the mineralization bedrock,biotite-granite,rich silicon,alkaline and potassium,and poor calcium,is beneficial to the molybdenum mineralization.And in this paper,geological characteristics of the molybdenum deposits are summarized,the alternations of the wall rock analyzed and the directions and indications for prospecting in the ore-forming and prospective zones come up with.
