Abstract

In this study, Talwani modeling method is applied to total magnetic anomaly map of Sinop and its surrounding area. As a result, the high anomaly values observed in the map were attributed to volcanic formations. The lower anomaly values were attributed to the effect of sediment cover. Tectonically structural elements existent in this area are evaluated as fault anomalies on the profiles in the magnetic map. The calculated average depth (1.5 – 8 km) values obtained during this model study are consistent with the former studies.
