摘要
通过对商州区马角寺一带钼矿床的区域成矿地质综合分析,钼矿床主要赋存于震旦系含炭质砂质板岩与寒武系碳酸盐岩接触部位的韧—脆性剪切带中,严格受构造破碎蚀变带控制,矿床属黑色岩系容矿的沉积—变质叠加—韧脆性构造改造的后生中高温热液成因矿床。
Analysis and researches on the regional geological background including regional stratum,structures,magmatic rocks,metallogenic geology and ore-controlling factors indicate that the molybdenum deposits in this area mainly occur in the ductile brittle shear zone of the Sinian carbonaceous slate and the contact zone of Cambrian carbonate rocks,which are strictly controlled by structural fracture alteration zones.The deposit belongs to the epigenetic medium high temperature hydrothermal deposit formed by the sedimentary metamorphic superimposition of the black rock series and the ductile brittle structure.
