This paper provides an investigation on describing the location of the boundaries and the vertical-horizontal dimensions of the causative bodies for Western Anatolia, Turkey. The selected study area has a crucial importance due to its location defined as one of the most rapid extensive regions in the world. Hence, it is essential to explore its structural properties and estimate the basement depth. To this end, several techniques such as tilt angle derivative, total horizontal of tilt, analytic signal are applied to aeromagnetic data of the study area. Firstly, the tilt angle derivative map is obtained from the arctangent of the ratio of vertical derivative to total horizontal derivative of the magnetic field. The map clearly shows the boundaries of the magnetic sources and they generally run along southwest-northeast directions due to the extensional regime. Moreover, using the half distance method on this map, depth of upper Turgutlu granitoid (TG) is calculated to be 4.5 km and 3.2 km for west and east, respectively. With those results, it is determined the locations of hot springs which are characterized by the low values in the tilt angle derivative map. Secondly, analytical signal method is employed to compute the basement depth. It is observed that the basement depth varies 1.4 km to 8.7 km beneath sea level. All the results and observations provide valuable insights about the region. They have a promising potential for 3D geophysical modeling of the study area as well.
