摘要
大兴安岭作为在古亚洲洋构造-成矿域基础上发展起来的北方造山带，具有多块体拼合增生造山的典型特征，中生代、新生代又受到多种成矿地质作用的改造和叠加，成矿条件十分优越，具备了大规模成矿的条件和潜力。这里在充分研究大兴安岭中南段地质构造、航磁特征的基础上，对航磁异常进行综合解释，寻找与成矿密切相关的中酸性岩体及其隐伏岩体和隐伏断裂构造等；利用成熟的地质异常理论与成矿勘探的思想，对大兴安岭中南段与多金属成矿密切有关的中酸性岩体、热液构造活动与二叠系等主要成矿地层的关系进行了研究，寻找与多金属成矿直接相关的地质复杂度高值区，进而圈定了研究区内的成矿有利地段。旨在为正在大兴安岭中南段的多金属矿产勘查提供一定的参考。
As the northern orogenic belt based on Paleo-Asian ocean tectonic-metallogenic domain,the Daxing'anling mountain had typical Features of the multi-block mosaic hyperplasia orogeny.Had reformed and superimposed in a variety of metallogenic geological processes in the period of the mesozoic and cenozoic,it enjoyed very favorable ore-forming conditions for forming potential large-scale mine.Based on deeply study of the geologic tectonics and aeromagnetic features of multi-metal mineral exploration,the author comprehensively interpreted the aeromagnetic anomalies,trying to find the buried neuter-acidic rocks and hidden faults closely related with the mineralization.And then,with the geological theory and mineral exploring techniques,the author analyzed deeply the relationship between neuter-acidic rocks,hydrothermal tectonic activity and permian-strata mineralization closed related in the middle-south section of Daxing'anling mountain in order to delineate the high value of geological complexity and potential ore-forming region.All of the above aims to provide references for multi-metal mineral exploration in this area.
