Özet:

Geomorphic records provide a fundamental research resource in understanding the role of active tectonics in the geological development of a field. Basin Bingol is in the eastern part of the Upper Euphrates Department Anatolia region of Turkey's Eastern. Bingöl Basin is a basin formed by many dextral and sinistral strike slip fault on the East Anatolian Fault Zone. The purpose of this study is to reveal the effects of active tectonism on morphology in Bingöl Basin. For this purpose, printed and digital geology maps active fault maps and topography maps, digital elevation model (DEM) with 10*10 m resolution, earthquake catalog data, Google Earth images and field observations were used. Geographical Information Systems (GIS) Technologies and geomorphological methods were used in the evaluation of the data. As a result of the study, it has been observed that the slope values of the Bingöl Basin and its surroundings changed in short distances with the effect of active tectonism. It was observed that many shapes such as suspended valleys, sag-ponds, triangular surfaces, linear valleys, offset rivers, occlusive ridges and pressure ridges were formed under the influence of active tectonism in the Bingöl Basin. In addition, we observed that landscape formed during Quaternary (alluvial fan, terrace etc.) have been deformed as a result of active tectonism in the Bingöl Basin. Our study shows that most of the active faults around the Bingöl Basin were missing in the previous literature, and morphological data should be taken into account more carefully in drawing active fault maps in the field.
