In this work we present a novel joint inversion scheme of Electrical and Electromagnetic (E&EM) data based on the full integration of system transfer functions and the decoupling of forward and model meshes. The EM data are modelled in 1D, while the galvanic data in 2D. The resulting joint models achieved unprecedented resolution and revealed entirely new resistivity structures, undetected in the independent models, while preserving a good data fit. This new joint inversion scheme has been applied to ten field survey across Europe and along the CSIRO Airborne EM calibration line at Perth, Western Australia. The validation of the independent and joint models is carried out with borehole comparison featured by both lithological description and logEM measurements. We believe that the E&EM joint inversion developed and applied in this study represents a breakthrough in the state of the art of galvanic and inductive investigations, pushing a significant step forward in high-resolution near-surface studies.
