会泽县娜姑镇银厂铅锌矿成矿条件及找矿方向研究

Study on the ore-forming conditions and prospecting direction of Yinchang lead zinc deposit in the Nagu,Huize county

会泽娜姑镇银厂铅锌矿床是赋存于下寒武统筇竹寺组地层中的裂隙脉状铅锌矿床。本文从地层、岩相古地理、地质构造、岩浆作用等方面分析了该矿床的成矿条件,指出了该区具有在下寒武统筇竹寺组地层中寻找构造控制的沉积—改造—后成矿床的找矿方向,对该区铅锌矿找矿有指导意义。

Yinchang lead zinc deposit in the Nagu town,Huize is a fissure vein lead-zinc deposit found in the formation of Qiongzhusi series of latter cambrian.In the paper,based on analyzing the ore-forming conditions from the aspects of stratigraphy,lithofacies palaeogeography,geological structure and magmatism,it is pointed out that there is a great potential for prospecting deposion-transformation-epigenetic deposit in Qiongzhusi series of latter cambrian,and it has guiding significance for future prospecting in this area.
