Abstract

The 3D-architecture of the Malatya Basin was studied using remote sensing, seismic interpretation, and palaeostress analysis in the context of the Malatya-Ovacik fault zone. The results indicate that the Ovacik and Malatya fault zones are not different segments of a single 'so called' Malatya-Ovacik fault zone; rather, they are two different fault zones that have operated independently. In addition, the Ovacik fault zone is delimited in the west by the Malatya fault zone, which extends farther north from the point of supposed junction. Maximum individual deflection of streams along the Ovacik fault zone is about 9.3 km, and summation of all stream deflections along different segments of the Ovacik fault zone indicates that sinistral displacement of the Ovacik fault zone has been not more than 20 km following development of the drainage system in the region.
