摘要
文章简要分析了安林铁矿区地层、构造、岩浆岩与成矿的关系,总结了安林地区东、西两个矿带的矿床地质特征,给出了该区的地质—地球物理找矿模型。通过分析安林地区各类岩石的物性差异及航磁异常与已知铁矿床的关系,指出应将工作程度较低的航磁异常、低缓磁异常及老矿山周边作为找矿工作的重点区域,配合多种物探方法相互验证,提高找矿成功率。通过前期的勘查工作,指出都里—清池一带可以作为下一步找矿工作重点突破区域。
This paper briefly analyzed the relationship among strata, structure, magmatic rocks and the mineralization, summa-rized the geological features of the both eastern and western ore belts in the Anlin area. and the geological and geophysical exploration model was constructed. Through analyzing the differences of physical property of all kinds of rocks and the relationship between aero- magnetic anomalies and known iron ore deposits, the authors proposed that those areas with less prospecting work in the aeromagnetic a- nomalies, weak magnetic anomalies and the surrounding areas of old mines are the focus of the future exploration. In combination of multi geophysical exploration approches, there is high chance of discovering iron deposits. Based on the previous exploration work, Du-li - Qingchi area is outlined as a key target area for next step of prospecting work.
