| 为了评价百吨沟金矿区深部找矿潜力,圈定深部找矿靶位,实现“攻深找盲”工作的突破,文中在阐述百吨沟矿区金成矿地质背景、矿(化)体及其地球化学特征的基础上,通过研究该矿区ⅪM1矿体的构造叠加晕特征,完善了前人在该区所建立的构造叠加晕深部预测模型,并进行深部找矿预测工作。结果表明:XI破碎蚀变带规模较大,其构造叠加晕特征反映出成矿作用具有向南东侧伏的规律,显示深部具有良好的成矿空间条件,找矿潜力较大；ⅪM1矿体向深部还有很大延深,深部盲矿可能较富,应加强深部找矿工作；通过赋矿构造带构造叠加晕特征研究,圈定出深部找矿靶位,为百吨沟金矿区深部探矿增储提供依据。 |

| In order to evaluate the prospecting potential in the deep of the Baidungou gold mine area and delineate a deeper ore-finding target and then to achieve breakthroughs in the task of “deep searching for blind”, this paper, on the basis of expounding the gold mineralization geological background, mineral body and geochemical characteristics of the Baidungou gold mine area, and study on the charcteristics of structural superposition hale of the XIM1deposit, has consummated the previously established modle of deep prospecting prediction of structural superposition hale and carried out the deep prospecting prediction activities. The results show that:①The size of the XI fracture zone is large, and its structural superimposed halo characteristics reflect that the ore-forming process has a regular pattern pitching to southeast and show that the deep part has good metallogenic space conditions, and the prospecting potential is greater; ②The XIM1 ore body is trending far in depth with a good potential for discovering deep blind deposits, so that the deep prospecting works should be strengthened; ③ Based on the study of the superimposed halos feature of the mineralization structure, further correction and delineation of the deep prospecting target should be carried out to provide a basis for the deeper exploration to accumulate resources and reserves for the Baidungou gold deposit. |
