| 摘 要： | 渭北航磁异常100nT以上的等值线圈面积大于4200 km2,有7个呈北东向排列的浓集中心,极值300—800 nT。异常区地质背景与山西临汾—万荣以铁为主的多金属成矿带一致,推测深部有隐伏岩体和邯邢式、沉积变质型磁铁矿床存在,预测铁矿资源潜力≥2.15亿t。建议开展深部找矿。

| Abstract: | The area outlined by isoline valued above 100nT of aeromagnetic anomaly surveyed in the north of Weihe is over 4, 200 km^2, in which 7 concentrated centers arranged at northeast direction have extreme value ranging between 300 nt and 800 nT. Geological background in the anomaly area is similar to the polymetallic belt in Linfen-Wanrong area in Shanxi Province. It is inferred that there would be Handan-type sedimentary metamorphic magnetite deposits containing over 215 million tons of iron resources in this area and ore prospecting in deep is recommended. |
