| 摘 要： | 以航磁异常为基本线索,分析了卫宁北山多金属矿床（点）、矿化带与磁异常的关系。利用电磁测深和重、磁2.5D联对反演对双石垒子航磁异常进行了综合解释,发现引起双石垒子磁异常源体密度与本区域分布的中酸性岩体密度值一致,证实了磁异常为中酸性岩体所致。结合区域地质背景条件和卫宁北山地表矿化及化探异常分布特征,推测本区断裂构造、岩浆岩与金、铜金、银铅多金属矿化之间的依存关系。同时,表明可能存在的隐伏中酸性岩体可能就是本区多金属成矿的源和中心,也是深部多金属成矿最核心的控制因素,从而为卫宁北山多金属矿勘查寻找提供了基本线索。

| Abstract: | Based on aeromagnetic anomaly as the basic clue,we analyzed Weiningbeishan multi-metal deposits (points) and mineralized belt and the relationship between magnetic anomalies.Using electromagnetic sounding and gravity and magnetic inversion of the pairs of 2.5D Alliance Air Shuangshileizi,we comprehensively interpreted the magnetic anomalies and found that the density magnetic anomaly caused by sub-source Shuangshileizi is the same as that of acid rock bodies in this area.According to the regional geological... |
