贵州省独山拉外硫铁矿床成矿地质特征

The mineralization feature of Lawai Pyrite Deposit in Guizhou Province

贵州省独山拉外硫铁矿床位于独山县城南东,区域内地质研究程度较高,尤其在地层学方面建立了我国泥盆系标准剖面。矿区内分布的地层为中泥盆统独山组鸡袍段、宋家桥段及鸡窝寨段,矿体呈脉状、透镜状赋存于一南北向断层中,含矿围岩为独山组鸡袍段蚀变粗晶白云岩、宋家桥段石英砂岩,断裂下盘赋存有异体共生的铅锌矿体及锑矿体,为低温热液矿床。

Lawai Pyrite Deposit is located in southeast of Dushan County, Guizhou Province.Geological studies of the area had a high degree in the past, especially constructed a standard section of devonian system in the stratigraphy of China.This paper conducts a series of exploration, identification ,lithology, main structure, orebody morphology, occurrence and characteristics of the ore quality future of the mine area, and makes the instructions for production.
