摘要
云南云县邦东铜铅矿体赋存于矿区内F1断裂破碎带及其两侧,尤其是两侧的次级断层与节理裂隙交叉复合部位,矿体更为富集。矿体围岩为上三叠统小定西组第二段(T3x2)的安山岩、安山玄武岩、玄武岩及硅化玄武岩。矿床成因属于火山岩蚀变过程中,於构造裂隙中充填-交代的中-低温热液型铜铅矿床。
The orebody of Bangdong Cu-Pb deposit in Yunxian, Yunnan is in F1 fault zone and its bothsides, especially more concentration in the secondary Suit and the intersection of joinwall rock of tlie orebody is Upper Triassic Xiaodingxi Formation Member 2 (T3X2) andesite, andesibasalt and silicified basalt. The genesis of deposit belongs to middle- low T hydrotliermal Cu-Pb deposit of filling metasomatism in structure fissure.
