摘要
内蒙古布敦花铜矿床位于大兴安岭多金属成矿带中段，东临嫩江深大断裂，与孟恩陶勒盖银铅矿，莲花山铜银矿，闹牛山铜矿构成一多金属矿化集中区。铜矿床的形成与燕山期中酸性杂岩体—布敦花岩体密切相关。成矿作用是在岩体不断演化过程中发生的。同位素地球化学研究表明，岩浆及成矿物质主要来自深部地幔。矿床形成属斑岩型。
Inner Mongolia Budunhua copper deposit is situated middle of polymetallic mineroge-netic belt Daxinanling.The copper deposit faces deep fracture of Nun River and consistsof polymetallic mineralization concentration area with Mengentaolegai silver lead,Lian-huashan copper-sliver and Naoniushan copper deposits.Forming the copper deposit isclosely related YanShan time middle-acid complex-Budunhua rock masses.The minero-gensis happen in the course of continuous evolution of rock mass.Isotopic geochemistryresearch make known magma and mineral-forming matter that mainly come from deepantle,The copper deposit beloiigs to porphyry type.
