| Abstract: | By use of a large amount of data on the earth's surface, we obtained informations which reflect the magnetic anomaly due to. the source within the deeper earth's crust by filter method. We have analysed the features of the anomaly's spatial variation, and compared them with the regional gravity anomaly, distribution of seismic belt and deep geological structure in the earth's crust and obtained useful results. |
