综合物探在会东航磁异常查证中的应用

摘要

According to the characteristics of the aeromagnetic anomaly in Huidong area,the authors have reached the conclusion that the aeromagnetic anomalies are caused by magnetic bodies in the depth.The integrated geophysical methods,which included ground precision-magnetic survey and audio magnetotelluric sounding (AMT),were used to inspect the aeromagnetic anomaly.Through combining the advantages of different geophysical methods,the authors improved the reliability of the geophysical interpretation.Using integrated interpretation of the data from gravity,magnetic survey and AMT,the authors initially identified the distribution characteristics of the anomaly body in the depth.The integrated geophysical results provide an ore-prospecting clue for the further exploration in this area.%根据会东航磁异常的基本特征,判断其异常为深部多个磁性体的综合反映.采用地面高精度磁测和音频大地电磁测深法,并结合区域重力勘探资料对异常区开展了综合物探调查.通过对区域重力、高精度磁法资料和音频大地电磁测深数据开展综合解释,初步确定了异常体在深部的空间展布特征,为在该区实施进一步的勘查工作提供了重要找矿线索.
