Abstract:
In this paper, we demonstrate wavelet analysis as a method of delineating the boundaries of subsurface geological structures. We apply 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 cross-sections. 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 Karliova and Kahraman Maraş region from NE to SW direction. |
