| 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...

| Abstract: | 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. |
