abstract = {We present the results of a direct current (DC)resistivity
and time-domain induced polarization (TDIP) surveyexploring
a copper ore deposit in Elbistan/Turkey. The ore depositis
elongated below a valley and is of disseminated form with
sulfidecontent. DC and IP data were acquired using the
pole-dipole arrayon eight parallel profiles crossing the
valley perpendicularly. Thelength of each profile was 300 m
with an inter-profile distance ofabout 50 m. The data were
interpreted by a newly developed 2DDC/TDIP inversion
algorithm. The finite element algorithm uses alocal
smoothness constrained regularization on unstructuredmeshes.
The finite element forward solution, as well as the
inverseproblem, is solved by an iterative preconditioned
conjugate solver.The depth of investigation (DOI) was
determined from cumulativesensitivities of the 2D inversion
algorithm results. Because of thedissemination of the ore,
the 2D inversion of the DC data wasambiguous: However, due
to the sulfide content, a strong chargeabilityanomaly
associated with the ore body was detected. Weshow that
chargeability anomalies can generally be detected in
theabsence or presence of corresponding resistivity
anomalies. Thishighly chargeable structure was confined in
lateral direction.Although the lower boundary of the
structure could not be resolvedby the applied field set-up,
a rough estimation of it could be derivedat a depth of 90 m
using synthetic modeling analyses. The 2Dchargeability
models are consistent with existing boreholeinformation.},
