In this paper, we have
first applied steerable filters to synthetic examples and after satisfactory
results are obtained; we have evaluated the tectonic setting of the Gelibolu
Peninsula in the western region of Turkey using potential fields. The gravity
and magnetic anomaly maps of Gelibolu used which was obtained from Turkish
Petroleum Research Institute (TPAO). A parallel fault branch on the North-West of
Anafartalar fault was detected. Also other tectonic structures of area were modelled. The results are confirmed by the TPAO
seismic data. Further it is shown that
steerable filters can be considered as a compromising approach in the
evaluation of geophysical data. In particular, they can be used to delineate
the strike of faults and to locate roughly ruins of foundation walls.
