The application of integrated geophysical methods to aeromagnetic anomaly inspection of Huidong area

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.
