The mountain range is located in the northwest of Iran between Ardebil province and East Azarbaijan (southern city of Sarab). Cenozoic volcanic rocks are widely distributed in the mountainous region. The faults and geological structures in the mountain range are often linear and arched. In this paper, using magnetic angle gradient and gradient filters in the range of mountainous buccal patterns, the hidden and submerged magnetic paths were detected. These angles of inclination and the horizontal gradient of the entire magnetic field are in perfect agreement with the structures, main faults and active geology in the mountain range. Subterranean structures in the range were also identified using these magnetic filters.
