In this paper is presented an integrated workflow using non-seismic methods (magnetotellurics, controlled source EM, gravity and full tensor gradiometry), showing how the inclusion of the information obtained by all these methodologies led to a better understanding of the geological settings over a salt diapir in the Nordkapp Basin, Offshore Norway. Single domain and joint inversions of the EM methods were both carried out, and the results validated using gravity and FTG forward modelling on a step-wise approach.
