| 摘 要： | 通过对冀东地区航磁异常的验证，磁测资料对于寻找埋深不大磁铁矿效果甚佳，对于铁矿埋深较大或者有赤铁矿的风化壳存在时，仅根据磁异常推断铁矿体的产状、埋深有很大的误差；在铁矿勘查工作时应用重磁综合的方法进行研究取得很好的找矿效果。

| Abstract: | The inspection of the aeromagnetic anomalies in eastern Hebei Province shows that the magnetic survey data are very effective in search for magnetite deposits at relatively shallow depth;nevertheless,these data have obvious limitations when they are used to deduce attitude and buried depth of an ore body according to the magnetism because of the error of reduction to the pole and the weathering crust.So the gravity exploration technique can play an important role in the iron ore exploration.The correct utilization of gravity-magnetic comprehensive methods can yield satisfactory ore-prospecting results in the work of iron ore exploration. |
