Abstract
Detection of the linear features is a useful task to understand the tectonism of a region. Gravity anomaly data was used to investigate the tectonic structures of SE part of Denizli, western Anatolia. This region is a tectonically active transition zone between Aegean extensional and Anatolian Taurides compressional provinces. Lineaments are appearance of the instantaneous change in the density of the subsurface rocks in gravity data. To determine the lineaments, derivative-based edge detection methods, horizontal gradient, analytic signal, tilt angle and hyperbolic tilt angle applied gravity anomaly data. In defining the lineaments, 3D sediment-basement model, elevation, geology and seismicity data were used comparatively. The sediment-basement topography was modelled by 3D inversion of gravity data. The maximum sediment thickness is defined 2.4 km in the northern part of Acipayam basin and 2.3 km in the southern part of Denizli basin. The earthquake distribution map, geology and elevation maps were provided insight the linear features of the region. As a result of the study, the new tectonic map is attained. Besides the known structures, many new lineaments and some buried faults were defined in the study area.
