| 摘 要： | 通过收集和研究莱芜富铁矿区早期的地面磁测资料,结合近几年在铁矿深部找矿中的理论及找矿实践,经过数据处理获得地面磁测ΔZ垂向二次导数异常,用以分解磁异常和圈定深部磁铁矿体的大致分布范围,在莱芜市石家泉地区找到了厚度较大的隐伏富铁矿体,初步估算铁矿石资源量在千万吨以上,取得了良好的找矿效果,同时对该地区深部铁矿找矿起到一定的借鉴。

| Abstract: | On the basis of collecting and studying ground magnetic datas in early period in iron-rich area in Laiwu city,combining with theory and practices of iron ore exploration in deep part in recent years,through the ground magnetic survey datas conduction,the second vertical derivative of ΔZ exception has been obtained in decomposition of magnetic anomalies and the delineation of the general distribution scope of magnetite in Laiwu city.Rather large hidden iron-rich body with great depth has been found in Shijiaquan area.It is preliminary estimated that the iron ore reserve is over thousands of tons.It will provide references for iron ore exploration in deep part. |
