Abstract
The main goal of this study is to delineate the subsurface structural features and depths of the causative sources in the Central Anatolian Crystalline Complex (Kirsehir Block), Turkey from aeromagnetic data. To this end, spectral analysis technique, analytic signal (AS) and tilt angle method were applied to the aeromagnetic data. The depths of causative sources were founded to vary between 8.48 km and 1.60 km. The AS and tilt angle method was implemented to regional anomalies and it was seen that the geological units defined by the field observation have a deeper root below the surface. In addition, although there are no rocks that have magnetic properties in the center of the geological map, the existence of a magnetized structure in the tilt map was determined. This phenomenon can be evaluated as the existence of a highly magnetized unit in the region that may have been covered by continental clastic rocks.
