Conference Paper / Summary Text
In this paper, we demonstrate wavelet analysis as a method of delineating the
boundaries of subsurface geological structures. We applied wavelet transform to Bouger
anomaly data of East Anatolian Fault Zone (EAFZ) and adjacent areas. Residual and
regional gravity anomalies of EAFZ lengthwise are separated using wavelet method.
Today Wavelet is one of the modern, stochastic image approaches processing technique
in earth science. The vertical, horizontal and diagonal components of wavelet output are
evaluated simultaneously and an underground model is obtained by suitable crosssections.
The tectonic evolution of the Eastern Mediterranean region is dominated by
effects of subduction along the Hellenic (Aegean) arc and of continental collision in
eastern Turkey (Anatolia) and the Caucasus. Eastern Turkey is instead experiencing
crustal shortening and thickening due to northward motion of the Arabian plate relative to Eurasia. EAFZ forms a 580 km left- lateral slip transform boundary between Karlƒova
and Kahraman Maraü region from NE to SW direction.
