The Çameli basin is situated at the southwestern Anatolia (Turkey), where is tectonically a very active region. The reduction to the pole (RTP), the upward continuation and the analytic signal (AS) methods were used in this study to determine the tectonic lineaments/bodies caused magnetic anomaly beneath the Çameli basin. The results show that the deep-seated magnetic bodies (at least 5 km deep) are possibly emplaced in the upper crust along the NE-SW trending faults. The AS map indicates that many of the causative sources appear elliptical shaped in the study.
