identification of tectonic lineation using airborne magnetic data in alborz, iran

The origin of the magnetic anomalies is the difference in spatial resolution of the rock mass magnetism adjacent to each other or it is due to the topography and structure of basement. available magnetic data is derived from aerodata corporation usa, in collaboration with the geological survey of iran from 1975 to 1977. the distance between of flight lines is 7.5 km and flight height is 250 m and the azimuth is 0°. also the type of magnetometer sensor used was cesium vapor magnetometer. all required filters are applied on the total magnetic field intensity to identify the surfaceand deep lineation. in this regard, the map is the base map of the magnetic data, which shows the total intensity of the magnetic field in the measuring points. the total magnetic field intensity is influenced by the material and magnetic structures present at that point. the igrf value of the land previously measured must be removed from the recorded data values displays the remaining amount of the anomalies in the area according to the angle of magnetic inclinationand declination.
