Lineaments are among the most important structural, geological, geophysical, and geomorphologic features that their identification has a significant impact on the exploration of important deposits and the prevention of the risks of earthquakes caused by these faults and lineaments. The use of airborne magnetic data is one of the efficient methods for identification of lineaments. In this study, various filters such as horizontal derivative filters, analytical signal and tilt angle are applied on the airborne magnetic data to identify faults and lineaments in part of southeast of Iran. Four lineaments are detected in this region in which the main faults of the region exist. These faults were detected in the maps drawn from the processing of the airborne magnetic data, and as a result, the hidden faults below the Quaternary sediments were detected.
