The study area of Sheikh Tabag-Mianeh is located in Alborz Azarbaijan zone,in NW of East Azarbaijan. The area is comprise of volcanic and sedimentary rocks of Eocean, Oligocean and Miocean type.The intrusion of granitoid body in NW- SE direction to these unites has caused reactivation of base metals and gold mineralization with their related alteration zones.

The recognition of surface and deep geological structures, setting of granitoid intrusion body & alteration zone can be used as an important exploration tools in prospecting the base metals and gold mineralization in the area. All these information extracted from airborne geophysical data (K,Th,U).

In this paper, for interpretation of airborne geophysical data in order to presentation the favorable zones of base metal and gold  have bean used from principal component analysis (PCA) and ternary image method. Resulted in detecting three promising areas of A, B and C for base metals and gold mineralization.
