Abstract
Determining and imaging the buried structures in underground is a widespread topic and the location and shape of buried structures can be determined detail with growing engineering technologies. Connection and analysis of the structure of the data is presented and obtained clearly by the edge detection filters. Upward continuation methods are applied to gravity anomalies for levels of 0.25, 0.50, 0.75 and 1 km. Total Horizontal Derivative (THD), Analytical Signal (AS), Tilt Angle Derivative (Tilt), Total Horizontal Derivative (THDR), Teta Angle Derivative (cosθ) and Hyperbolic Tilt Angle Derivative (HTA) are performed to upward continued gravity anomalies of study area respectively and the discontinuities and the boundaries of the geological structure are determined in the basin area. Tilt and Teta angle derivatives are given the best results from the applied derivative filters. The obtained results are compared with the existing surface geology. In addition to the discontinuities determined from surface observations, new structures and discontinuities are found from obtained results.
