Özet

In this paper, we demonstrate the effectiveness of steerable filters as a method of delineating the boundaries of subsurface geological structures. Steerable filters, generally used for edge detection on 2-D images, have the properties of band pass filters with certain directions and are applied to many image processing problems. We first tested the method on synthetic data and then applied it to the aeromagnetic data of Iskenderun Basin and adjacent areas.

 

In this paper, we demonstrate the effectiveness
of steerable filters as a method of delineating
the boundaries of subsurface geological structures.
Steerable filters, generally used for edge detection on
2-D images, have the properties of band pass filters
with certain directions and are applied to many image
processing problems. We first tested the method on
synthetic data and then applied it to the aeromagnetic
data of _Iskenderun Basin and adjacent areas.
_Iskenderun Basin is located in the Northeastern
Mediterranean where African–Arabian and Anatolian
plates are actively interacting. The basin fill records a
complex tectonic evolution since the Early Miocene,
involving ophiolite emplacement, diachronous collision
of Eurasian and Arabian plates and subsequent tectonic
escape related structures and associated basin
formation. Geophysical investigations of the tectonic
framework of _Iskenderun Basin of Turkey provide
important insights on the regional tectonics of the
Eastern Mediterranean and Middle East. In this study
we show geological structures, which are responsible
for the magnetic anomalies in _Iskenderun Basin and
enlighten the structural setting of the Northeastern
Mediterranean triple junction using steerable filters.
We obtained a magnetic anomaly map of the region
from the General Directorate of Mineral Research and
