ISPARTA AÇI BÖLGESİ (GÜNEYBATI TÜRKİYE) YAPILARIN SINIR TESPİTİ VE DERİNLİK TAHMİNİ ÜZERİNE HAVA MANYETİK VERİLERLE BİR ARAŞTIRMA

Abstract

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.
