The diapir structural complexity, as well as the ductile deformation style makes the field data extrapolation in depth a difficult task. Consequently the arrangement of geophysical data to determine the geometry of the diapir in depth becomes essential. In the external Prebetics, where the diapirs are made of evaporitic rocks and the cover formed by carbonate rocks, lithologies with very different range of resistivity suggested the magnetoteluric method as the ideal for this zone. The application of Magnetoteluric method in the Bicorp-Quesa diapir has allowed: 1) To recognize a basement fault that sinks 700m the northern platform. 2) To figure out that this fault was active during the Mesozoic. 3) To precise that the diapir is formed by Upper Triassic facies made by salt in the core and by clay and mudstones below the platforms
