This paper aims to delineate the subsurface structures and their depths located in the Isparta Angle region (SW Turkey) through the aeromagnetic data. The dataset has been processed via the well-known mathematical tools such as spectral analysis and derivative methods. First, to separate these anomalies from each other, the spectral analysis has been completed and high anomaly regions have been determined around Isparta city. This could be attributed to the fact that these values might be stem from magnetic bodies (like volcanic cones, caldera) located in the Golcuk volcanic region. In addition, the average depths of deep and shallow causative bodies have been calculated to be 6.72 km and 0.31 km, respectively. Secondly, to delineate the exact location and the depth to top of the sources, analytic signal transformation and tilt method have been applied to the residual anomalies. The maps show six regions which have the high magnetization values and these anomalies have been investigated in detail to delineate the upper depths of subsurface structures. Especially, the study showed that Golcuk volcanic occurrences, which are one of the crucial structures in the region, have a deeper root (around 3.47 km) and larger lying magnetic bodies underneath the surface.

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.
