摘要
陕西省商洛市商州区南台钼矿床赋存于秦岭纬向构造带北部汤峪—板桥构造带东段南缘。矿体产于元古宇长城系宽坪群广东坪组一套中深变质的绿片岩类岩石与大理岩类岩石组成的碳酸盐岩夕卡岩带和沿F42断裂分布的霏细(石英)斑岩中。区内的岩浆活动、矿体的产出形态及矿化富集规律等均与该区的主要断裂构造F42有着密切的关系。通过对该矿床的成矿地质特征、矿化富集规律等的总结,初步探讨了该矿床的成因及控矿因素,分析认为矿床深部具有很大的找矿潜力,具有寻找斑岩型钼、钨矿床的有利条件。
The Nantai molybdenum deposit, located in the Shangzhou district, Shangluo city, Shannxi Province, occurs at the southern edge of the eastern part of the Tangyu - Banqiao structural zone in the northern Qinling latitudinal tectonic belt. The ore bodie s at the carbonated skarn zone formed by the green schist rocks and marble of the Guang dongping Formation of Proterozoic period and felsitic （quartz） porphyry distributed along the F42 fault. There is a close genetic relationship between magmatic activity, orebody distribution and mineralization enrichment regularity etc. and the activity of the region major fault of F42. Through summarizing the metallognetic characteristics and mineralization regularity, the deposit genesis and ore - controlling factors were discussed. By the integrated analysis, it indicated that there is a great prospecting potential in the depth of the deposit, there is favorable conditions for exploring the porphyry type molybdenum and tungsten deposits in the region.
