| | Abstract | | Reliable and reasonable 3D models of physical properties, which can be recovered from 3D inversions of geophysical data, are required to interpret complex geological structures appropriately in 3D. However, the geophysical inverse problem is ill-posed, i.e., non-unique and unstable, especially for the case of 3D problem. Appropriate 3D a priori model can help solving this problem. In this study, we have performed 3D inversions of MT, Gravity, Magnetic data acquired in Yamagawa geothermal area, with 3D a priori models help recovering more reliable and reasonable 3D models of physical properties. Also, these results can help interpreting the complex geological structures in the surveys area. |
