| 摘 要： | 那郎金矿位于"南盘江—右江成矿区",为典型的微细粒浸染型金矿。文章通过对那郎金矿的地层、构造和围岩蚀变等综合分析,总结矿床地质特征和成矿控矿因素,确定找矿标志,建立了综合找矿模型,探讨了找矿方向。研究表明,该矿区的赋矿围岩为三叠系下统罗楼组第一段和二叠系上统吴家坪组;矿体及矿化体的控矿构造主要为近南北向、北西向、南东向断裂构造;与金矿化密切相关的围岩蚀变为硅化和黄铁矿化。

| Abstract: | The Nalang gold deposit, located in the Nanpanjiang-Youjiang metallogenic region, is a typical fine grained disseminnated gold deposit. Based on comprehensive analysis of strata, structure and wall rock alteration, geological characteristics and ore controlling factors of the deposit were summarized. The prospecting criteria was determined and the comprehensive prospecting model was set up and finally the further exploration direction was pointed out. The study result shows that the ore-bearing strata in the area are Upper Triassic Luolou formation and Upper Permian Wujiaping formation. The ore-controlling structures are mainly the north-south, northwest and south-east trending faults. The wallrock alteration closely related to gold mineralization is silicification and pyritization. |
