The various data processing techniques, to illuminate the parameters of the geologicalstructure which are applied in gravity and magnetic potential field methods. Also edgedetection procedures are in data processing techniques. In this study, 2D, 3D, inversionand asta technique is one of the new edge detection procedures were applied to clarifycorrelation between the Simav half graben’s deep position and geometry of the tectoniclineaments. The Asta is obtained using the tilt angle
