| 中文摘要: |
| 西藏自治区安多县抱布德铜铅矿位于班公湖—怒江铜多金属成矿带中段,塞可塘—巴格日陇巴—阿尔下穷断裂带南侧。区内构造活动强烈,具有良好的成矿地质条件。抱布德铜铅矿属于受地层和断裂构造控制的中低温—中高温热液充填交代型矿床。矿区矿体围岩蚀变明显,地表矿体顶、底板围岩中有硅化、碳酸盐化现象。该矿区各元素异常主要沿背斜核部的土门格拉组一段灰岩分布,异常浓集中心受北西向断裂构造控制,在构造带、次级裂隙等有利成矿地段各元素含量相对较高,是寻找铜铅多金属矿的有利部位。 |
| 英文摘要: |
| Lead mine in Baobude,Anduo County,Tibet Autonomous Region locates in the middle of Bangong Lake-Nujiang Copper polymetallic mineralization belt and south side of the fault zone in Sai ketang-Bagerilongba-Alxiaqiong. There are strong tectonic activities and good mineralization conditions in the region. Lead mine in Baobude which controlled by strata and faulted structure is a low temperature-high temperature hot liquid filling metasomatic deposit. The alteration of mining area ore body surrounding rock is obvious, having silicification and carbonatization phenomenon between surface orebody top and surrounding rock bottom. Elements anomaly mainly distributes along the anticlinal core of Tumen Gela Group- limestone in this mining district, the center of abnormal concentration controlled by the northwest trending faulted structure, elements content is more relatively higher at favorable mineralization lot, such as Tectonic Zone,Secondary Cracks and so on. It proves that the relation between faulted structure development degree and so on of the abnormal region and tectonic activity is very closely in abnormal area and there is a favorable position to look for copper and lead metal ores. |
