      abstract     = {The joint application of the Direct Current Resistivity
                      (DCR) and Time-domain Induced Polarization (TDIP) methods is
                      a helpful tool to investigate ore deposits with sulfidic
                      content. The combined interpretation yields a resistivity
                      and chargeability model of the subsurface which is superior
                      to a pure resistivity model, especially when dealing with
                      disseminated deposits.We present a newly developed
                      smoothness constrained 2D inversion algorithm for DCR and
                      TDIP data applying a two-step approach. It contains a Finite
                      Element forward calculation on an unstructured triangular
                      mesh which amongst others simplifies the incorporation of
                      topography.The new algorithm is tested regarding the quality
                      of the chargeability resolution with respect to the
                      resistivity model. Furthermore, the resolution of the lower
                      boundary of a highly chargeable model block is investigated
                      and compared to the depth of investigation which is
                      determined by the coverage matrix.Finally, 2D inversion
                      results of field data acquired on a sulfidic copper ore
                      deposit in Turkey are shown using the newly developed
                      algorithm and a feasible interpretation is given.},
