江苏南京西横山地区铜金矿找矿潜力

Prospecting potential of copper and gold ores in the Xihengshan area of Nanjing, Jiangsu Province

通过对江苏南京西横山地区地质背景、地球物理场、地球化学元素综合异常特征的综合研究,认为西横山地区既有寻找接触交代型金铜矿、热液充填型铜金矿和斑岩型铜金矿的成矿地质背景条件,又有良好的重、磁、电和地球化学元素综合异常反映。结合沿江Ⅳ级成矿带找矿模式和獾子洞铜金矿、上湾塘金矿典型矿床重磁场特征分析,对江苏南京西横山地区铜金矿找矿潜力进行了探讨。

This work comprehensively studied the geological setting, geophysical field and geochemical element anomaly characteristics of the Xihengshan area, Nanjing, Jiangsu Province. It is indicated that the Xihengshan area has geological background conditions for searching for contact metasomatic gold-copper deposits, hydrothermal filling copper-gold deposits and porphyry copper-gold deposits, as well as comprehensive anomaly reflection of gravity, magnetism and geochemical elements. Combining with the prospecting model of IV-order metallogenic belt along the Yangtze River and the analysis of gravity and magnetic field characteristics of typical deposits of Xihengshan copper-gold deposit and Weizidong copper-gold deposit and Shangwantang gold deposit, this work also discussed the prospecting potential of copper-gold deposit in this area.
