      abstract     = {We present the application of a newly developed 2D direct
                      current (DC) resistivity and time-domain induced
                      polarization (TDIP) inversion algorithm on synthetic and on
                      field data. The algorithm applies local smoothness
                      constraints and error weighting. The inversion is conducted
                      in two steps. First, an effective resistivity model is
                      obtained from inversion of the measured apparent resistivity
                      data. Subsequently, a non-linear IP inversion is applied
                      resulting in a chargeability model of the subsurface. The
                      implemented forward calculation uses the Finite Element (FE)
                      method. Unstructured triangular meshes are used for all
                      forward and inverse calculations allowing the incorporation
                      of complex surface topography in the inversion mesh. A
                      modeling study with synthetic data shows that the algorithm
                      is capable of resolving chargeability anomalies independent
                      from the corresponding resistivity anomaly. This is
                      important for disseminated deposits, since the resistivity
                      signature of finely distributed material might be
                      insignificant whereas the IP effect of ores, especially
                      sulfides, is strong. The inversion of DC/TDIP field data
                      acquired on a (mainly disseminated) copper ore deposit in
                      Turkey reveals a strong IP effect, as expected, which is
                      interpreted to be caused by sulfidic copper ore content.},
