摘　　要：冷水沟—南沟矿区位于南秦岭印支期褶皱带东段。区内发育有冷水沟斑岩型铜矿床和南沟构造热液脉型金矿床。本文通过对南沟金矿区的成矿地质特征进行总结,发现区内金矿体主要赋存在斑岩体外围的基底构造层及与岩体的外接触带中。矿床成因属岩浆热液蚀变型、韧性剪切带型金矿床,结合冷水沟斑岩型铜矿成矿特征构成斑岩型矿床的成矿系列。综合分析认为本区具有良好的找矿前景,在柞水—山阳矿集区有望形成大型铜金矿床的突破。Lengsliuigou - Nangou deposit is located in the eastern indosinian Hercynian folding belt of Southern Qin- ling orogenic belt. Lengshuigou porphyry copper deposit and Nangou tectonic hydrothermal vein type are also found inside the metallogenic belt. Through the comprehensive analysis of tlie metallpgenic tures in Nangou gold deposit, it is thought that the orebodies are controlled by basement tectonicperipheral and rock mass external contact zone. This deposit is a typical magmatic hydrotliermal corrosion variant and ductile shear zone type gold deposit, which integrated Lengsliuigou porj^hyry copper deposit constitutes the met- allogenic series of porphyry type deposit. It is believed that this mining area has a favorable prospecting potential, and it is possible to find a large-sized gold deposit and achieving significant exploration Shanyang mineralization region.
