Abstract

In this research which is done for the purpose of exploration, we try to specify the effective criteria in knowing the MINERALOGY by using study tools and new methods in order to use them for identifying the mineral potentials.Present studies are geology studies and preparing geology and ALTERATION map in north and north–west of Ahar in KIGHAL area with an area of 12 km2 and a SCALE of 1: 5000.The lithologic units of area are igneous volcanic and sub-volcanic rocks which have been formed in eocene to quaternary periods that included andesit, tuff, agglomerate, tracy-basalt and intrusive rocks of porphyritic granodiorite and porphylitic monzodiorite with nature of sub-volcanic, and lavas and basic volcano domes of plio- quaternary with compositions of basalt and andesite.Alteration in this area are related to activity of hydrothermal fluids resulting from intrusion of oligocene sub-volcanic rocks with composition of granodiorite in north-east and monzonite, dacite and riolite in west of area and numerous dikes have been occurred that north-eastern part of KIGHAL is considered as the most important restricted area from the view point of mineralization. This ALTERATION is included propylitic, argilic, advance argilic, serisitic and potasic that have same zoning with porphyritic systems in the area's ALTERATIONs and the presence of mineral creation of ore copper as stockwork in potasic zone in these ALTERATIONs are helpful evidence which are vigorated the probability of the presence of porphyritic system in this area.
