摘要
通过对内蒙古布敦化铜矿床不同类型岩石和金属硫化矿物的稀土元素地球化学特征的研究,并进行了有关稀土元素地球化学参数的计算,建立了相关的稀土元素球粒陨石标准化配分模式图。笔者认为布敦化矿区成矿物质的来源具有多样性,矿床、岩体和地层在成矿元素上具有密切的内在联系:下二叠统地层是成矿的物质基础,而燕山期岩浆侵入是成矿的关键。同时,根据矿区硫化物矿物的δEu正、负异常特点,认为布敦化矿区成矿作用具有复杂性和多阶段性。
From studying on the geochemical analysis of the rare earth elements(REEs) in different types of rocks and metallic sulfides, and calculating the related geochemistry parameter of the REEs, REE patterns of rated rocks and metallic sulfides after chondrite-normalizing are established. It is concluded that the ore sources of Budunhua copper deposit have diversities; the copper deposit, rocks and stratum have an intrinsic connection: the lower permian stratum is the material basis of mineralization, and the YANSHANNIAN magma intrusion is the sticking point of mineralization. At the same time, through theδEu positive and negative characteristics, the author considers that the mineralization of Budunhua copper deposit is complicated and multi - stage.
