燕山地质期的大规模岩浆活动,在大兴安岭地区演化形成多种岩浆岩系列,其中以中酸性杂岩与多金属成矿间专属性议题,引发人们对其更多思考,借鉴典型矿床实例,在大罕山新发现铜锡多金属成矿,是目前在大兴安岭中段成功找矿案例。深入探讨大兴安岭中段燕山期中酸性火山侵入杂岩与多金属的成矿,对大力开展该区找矿无疑具有重要的意义。
Large-scale magmatic activities during the Yanshan geologic period have evolved into a series of magmatic rocks in the Greater Khingan Range. Among them, the topic of specialization between intermediate-acid complexes and polymetallic mineralization has triggered more and more people’s thinking on it. Drawing on typical examples of deposits, The newly discovered copper-tin polymetallic mineralization in the mountain of Dachan Mountain is a successful case study in the middle section of Daxinganling. It is undoubtedly of great significance to further explore the mineralization of mid-acid volcanic intrusive complex and polymetallic in Yanshanian in the middle section of Daxinganling.
