INTERPRETATION OF MAGNETIC DATA USING BOUNDARY ANALYSIS AND INVERSION TECHNIQUES: A CASE STUDY FROM GÖLCÜK/ISPARTA (TURKEY) REGION

The Gölcük (Isparta) is on the southern side of city Isparta in Mediterranean region Turkey. investigation magnetic field strength variations over subterranean layers may reveal their locations Earth?s surface and provide physical geometrical characteristics. Magnetic studies were carried out around caldera lake using proton magnetometers to identify subsurface volcanic structures. acquired data inverted four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, results used determine anomalous We also pseudo-gravity reduction-to-pole techniques for interpretation. Additionally, evaluated power spectrum technique compared with 2D 3D prismatic inversion outcomes. As a result, boundaries depth structures, trachytic dome south determined three cross-sections areas. show that structures? average values vary between 225 m 391 maximum Caldera reaches up 1076 m.
