Evaluation of the Tectonic Boundaries Using Potential Data at Al-Tharthar Lake and Surrounding Area, Middle of Iraq

Abstract

The gravity and magnetic data of Al-Tharthar lake and surrounding areas in central Iraq were considered to study the tectonic situation in the area. The residual anomalies were separated from regional using the polynomial method with three orders. The Total Horizontal Derivative anomalies of gravity and magnetic are used with the residual anomalies to identify the faults and their trends with the basement rocks. The predominant trends are approximately N45W and N60E. Many faults and tectonic boundaries were detected and traced on the tectonic map of the study area.
