| Summary |
Magnetotellurics (MT) provides images of low resistivity alteration characteristic of hydrothermal alteration generally associated with active up flow. The accuracy of the resistivity images is therefore an important factor in defining the conceptual model. The sensitivity of the MT decreases with depth. To improve the geophysical image, we investigate how to combine MT, gravity and drilling data in the Asal Rift region of the Republic of Djibouti. In this study, we present a new gravity inversion approach constrained by a 3D MT resistivity model on the Asal Rift data. The results are conclusive and promising in the application to natural resources exploration. |
