摘要
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 paper discusses metallogenesis in the middle and southern segments of the Great 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.
