The 1:100000 sheet of Halab is located between 48 to 48 30' eastern longitudes and 36 to 36 30' northern latitudes, in the Zanjan Province. Soltaniyeh Mountains trending NW are situated in the north of the sheet. From country subdivisions viewpoint, the area includes parts of the Ijrud and Qidar counties.
Aeromagnetic survey was conducted between 1974 and 1977 by US Service Areo Co. Distance of flight lines is 7.5 Km, while the distance of and tie lines is 40 Km.
The aim of this study is to determine magnetic lineaments and large faults, identify magnetic anomalies and their correlation with geology, and identify sub-volcanic intrusive bodies.
In this study, we applied the weight of evidence method to various data layers in the sheet to prepare the metallic mineral potential map of it. By this method, the probability of mineralization in the Halab area was determined that is plotted as black regions in the map.
