In the abstracts we described the approach to fulfil CSAMT soundings and data processing in frequency range 16-45000 Hz using newly developed broad band electromagnetic receiver ARMT-5 for study the geological structure of salt deposit in Perm region, Russia. We discussed main features of new equipment including portable inductive magnetic sensors, general CSAMT processing framework, static shift problem and inversion results. Analysis of equivalency of obtained models and comparison inversion results with borehole data allows to conclude that applied methodology allows to map the resistive salt layer and conductive thin layer of ground water with high mineralization above the salt layer and conductive zone below the salt layer. Applied frequency range of CSAMT data in this case had the depth of investigation up to 250-400 m.
