摘　　要：成矿物质来源及控矿因素是矿床学研究的前沿课题。过去人们认为成矿物质主要源于含矿围岩的萃取。因此,找矿重点是寻找矿源层。但是,更多的事实表明,成矿物质主要来自深源,通过地幔热柱多级演化迁移至地壳,并在幔枝构造较好的控矿构造空间聚集成矿。本文探讨了大兴安岭中南段的成矿作用,总结了该区的主要控矿构造,指出了不同级别构造对成矿的控制作用,并预测了不同级别的成矿靶区。The source of metallogenic and ore-forming factors is a frontier topic for study of mineral deposit. In the past, people ever thought that metallogenic element was mainly derived from ore-bearing wall rocks. Therefore, ore prospecting was cast about for source bed. But, in fact, it is now indicated that ore-forming materials are mainly derived from a deep source. The metallogenic materials migrating along with multistage evolution of the mantle plume have been collected by favorable ore-controlling structures of mantle branch. Based on the working idea, this article discusses metallogenesis in the middle and southern segments of the Da Hinggan Mts, outlines the major ore-controlling structures, and reveals the control mechanism for ore formation of different grades. A favorable exploration targeting area has been predicted.
