摘要
白音诺尔铅锌矿床是内蒙古典型的夕卡岩型矿床,但有关该矿床的成矿岩体的地球化学及成矿动力学尚缺乏研究和报道.本文选取了与成矿密切相关的花岗岩类开展相关的研究,结果表明:岩石整体为高钾钙碱性系列,富集轻稀土元素与大离子亲石元素(LILE),相对亏损高场强元素(HFSE),岩浆起源为富集地幔,成矿作用发生于造山后的伸展拉张环境.
The Baiyinnuoer Pb-Zn deposit in Inner Mongolia is a typical skarn type deposit. However, there is little research concerned with geochemistry and metallogenic dynamics of the ore-forming body. The granitoid rocks that related to mineralization are studied in this article. The results show that the granitoids are high-K ic-alkaline series with enriched LREE and large-ion lithophile elements (LILE) and depleted high field strength eIem (HFSE). The origin of magma is the enriched mantle. The mineralization occurred in the post-orogenic extension environment.
