Joint inversion of EM and magnetic data for near?surface studies

Résumé

Magnetic and electromagnetic measurements are influenced by magnetic susceptibility and, thus, are widely used in geophysical surveys for archeology or pedology. To date, the data inversion is performed separately. A filtering process incorporating both types of data is presented here. After testing the algorithm with synthetic data, the algorithm is used in several case studies in archeological prospecting. This approach presents two advantages: establishing the presence of remanent mag-netizations (viscous or thermoremanent), and achieving more refined depth analysis of the anomaly.
