Integrated geophysical investigation of the Galatian Basin around Seben region, Bolu, Turkey

Three-dimensional (3D) and two-dimensional (2D) modelling studies were constructed on the gravity anomaly data to reveal the basement structure of the basin. Findings were compared with the interpretation of seismic sections. Depth of the western part of the Galatian Basin varies between 3 and 12 km, and the basin deepens through the east encouraging acquisition of new seismic data and drilling wells in the deeper part of the basin to the east. The westernmost part of the basin was divided into two sections by a saddle extending from Seben to Mudurnu in the NW-SE direction and the basin gets deeper again to the south of Mudurnu, down to 6-7 km.
