摘要
北大山铅锌多金属矿于2015年被发现,是以铅锌为主要有用元素的岩浆热液型多金属矿床,综合分析了矿床地质特征,认为矿床成因与岩浆热液作用密切相关,成矿流体主要为岩浆水,成矿物质主要为幔壳混合来源。矿体受蚀变细粒花岗岩和北东向压性断裂构造联合控制,绿泥石化、褐铁矿化及多金属硫化物蚀变是矿(化)体赋存的主要标志。
The BeiDashan Pb-Zn polymetallic deposit was discovered in 2015 year,it is a polymetallic deposit of Magmatic-hydrothermal type which is maily formed by Pb-Zn as useful elements.Based on a comprehensive analysis on the geological characteristics of the deposit,it is believed that the genesis of deposits was closely related to the magmatic hydrothermal activity.The metallogenic fluid is mainly magmatic water.The source of ore materials is crust-mantle mixture.Ore bodies are controlled by altered fine grained granites and NE trending compressional faults.Chloritization,sericitization,limonitization and polymetallic sulfide alteration are the main indicators of mineralization.
