山东省昌邑-平度地区航空电磁法测量及应用效果

MEASUREMENT AND GEOLOGICAL EXPLAINATIONAREA,SHANDONG

摘要:

航空电磁法测量是一种成本低、效率高的快速找矿方法，它是以地质体导电、导磁性能的差异为物理基础的。昌邑—平度地区构造较为复杂，并被第四系覆盖，使用双频（４６３Ｈｚ和１５６３Ｈｚ）电磁仪的Ｙ１１航空物探（电／磁）综合站，在该区飞行３０００余公里，其电磁法资料较清楚地显示了区内断裂构造及石墨、铁矿（化）体的赋存展布情况，取得了较好的效果。

Abstract:

Airborne electromagnetics is a rapid minerals prospecting method with low cost and high effect.The differences of conductance and magnetism of geologic bodies are its physical base.The structure in Changyi-Pingdu area is relatively complicated and the area covered by Quaternary system.Detailed airborne electromagnetic datas have been gained by the Y-11 airborne geophysical exploration station which is equipped with dual frequency electromagnetic meter after flying over 3000km.These information clearly s...
