| 摘 要： | 中生代时期由于受太平洋板块俯冲作用的影响，大兴安岭地区产生强烈的火山-次火山作用.以中生代火山断陷区为构造背景，火山断陷区的边部与断隆区交接部位形成了大量的铅锌多金属矿化.矿床基本受一套火山岩-潜火山超浅成侵入体-浅成侵入体控制，铅锌矿化作用基本与火山-次火山作用同时进行，略有滞后，并受火山-次火山活动制约.大兴安岭主要有6个有成矿潜力的铅锌成矿带：（1）得尔布干铅锌（金、银）成矿带；（2）谢尔塔拉-阿尔山铅锌多金属成矿带；（3）乌兰浩特-林东铅锌多金属成矿带；（4）林西-黄合吐铅锌多金属成矿带；（5）锡林浩特-朝不楞铅锌多金属成矿带；（6）小东沟-翁牛特旗铅锌多金属成矿带.共有3种铅锌矿化形式.

| Abstract: | Due to the subduction of the Pacific plate in Mesozoic Era, severe volcanic-subvolcanic activities took place in the Daxingauling region. On the tectonic background of Mesozoic volcanic fault depression, amounts of Pb-Zn polymetal mineralization occur on the margin of the fault depression and the in the connecting belt between depression and uplift. The deposits are controlled by a series of volcanic-subvolcanic hypabyssal intrusive. The mineralization is formed nearly the same as or slightly later than the volcanic-subvolcanic activities. Six potential Pb-Zn metallogenic belts are recognized in the Daxinganling region, i.e. 1 ） Derbugan Pb-Zn（-Au-Ag） metallogenic belt; 2） Xiertala-Arshan Pb-Zn polymetal metallogenic belt; 3） Ulanhot-Lindong Pb-Zn polymetal metallogenic belt; 4） Linxi-Huanghetu Pb-Zn polymetal metallogenic belt; 5） Xilinhot-Chaobuleng Pb-Zn polymetal metallogenic belt; and 6） Xiaodonggou-Ongniud Pb-Zn polymetal metallogenic belt. The deposits can be assigned into three metallogenic types. |
