Investigations into geological structure of Gulf of Saros and Gelibolu peninsula by using airborne magnetic data

The paper aims to investigate the geological structure of the Gulf of Saros and Gelibolu peninsula by using airborne magnetic data. To this end, derivative methods such as the second vertical derivative and tilt method have been applied to these data and created the anomaly maps. By a closer look at these maps, it is observed that there is an intense linear magnetic anomaly parallel to the shoreline of the Çanakkale Strait. This intense anomaly can be correlated with the Ganos Strike-slip Fault observed in the north-western part of the active tectonic map of Türkiye. In addition, the depth estimations utilizing the half-width method for simple geometric bodies suggest a deep source in the southwestern profile and a shallow source in the northeastern profile. As a result, it can be deduced that the magmatic material arising from the magma fills inside the strike-slip fault causing this magnetic anomaly. Such sources with deep roots could be prospective for geothermal energy as well as hydrocarbon maturation.
