Özet

The Galatian Basin in the northern part of the Central Anatolia is a large, but insufficiently investigated and unexplored basin because of the volcanic cover on the surface. Its great dimensions can only be noticed when the gravity anomaly map of Turkey is examined. In this paper, it is aimed to investigate the subsurface structure in the western part of the Galatian Basin around Seben region, Bolu. The reason behind the study of only western part of the basin is the existence of seismic and a single borehole data that allow the comparison and control the results of potential field modelling studies in integration. The gravity and aeromagnetic anomaly data were processed with the advance potential field data processing methods. Analytic signal method was performed on the aeromagnetic anomaly data to determine the possible erupsion centers of the volcanic rocks on the surface in and around the Galatian Basin. According to the Analytc Signal transformation results, there are two possible eruptional area; one of them is located to the south of Bolu and the second one is around the W-NW of Ankara, the capital city of Turkey.
