Geological lineament analyses application to a fault segment on the east anatolian fault zone

Abstract

Geological lineament analyses were performed on the segment of East Anatolian Fault Zone between Doganyol (Malatya) and Celikhan (Adıyaman) in eastern Turkey. The Eastern Anatolian Fault Zone is one of the important intra-continental strike-slip faults in the Alpine-Himalayan Orogenic Belt. A detailed analyses along the fault segment using satellite images (LandSAT 8 OLI, ASTER image) and digital elevation models (DEMs) were brought out that the fault segment presents geological lineament and morphotectonic structures based on filtering and enhancement methods. Filtering and enhancement processes of satellite images realised using Arc Map 10.2.2 and ENVI 5.1 softwares. Extracted lineaments along the fault segment were evaluated in rose diagram and compared with morphotectonic structures and regional tectonics. Consequently; obtained dominant lineaments and observed morphological data compatible with the East Anatolian Fault Zone. Other lineaments are conjugate of the East Anatolian Fault Zone. © SGEM2019.
