Anniq exploration area with 19 km2 space, is located in Jolfa city, East-Azarbaijan. The area is a part of Tertiary- Quaternary magmatic zone (Stocklin, 1977) and lies in Arasbaran- Garadagh height which in the following joins to small Caucasus magmatic belt. The most important geologic feature in the area is Ordubad granitoidic complex are injected into upper-Cretaceous flysch- like rocks to Eocene and in its contact place extensive hydrothermal alteration and skarn deposits are developed.
Bedrocks outcrops in Anniq exploration area include granodioritic part of Ordubad batholith which is occupying large part of the area. Between Aghan and Garachilar villages and in the marginal part of Anniq river, multiple quartz- monzonitic dikes with porphyritic texture with microcrystalline matrix and siliceous veins with Cu-Mo and Au mineralization, cut granodioritic body. The dominant trend of these dikes and veins are E-W to NW-SE.
Mineralization in this body consist of pyrite, chalcopyrite and molybdenite . Molybdenite and chalcopyrite mineralization is mainly observed in siliceous veins. Mineralization in Anniq granitic stock is mainly pyrite and its main alteration is carbonization and sericite. Quartz-Monzonite dikes have moderate to severe phyllic alterations and Cu, Mo and Au mineralization can be seen in them.Regarding these dikes focus between Aghan to Garachilar villages seems that there is a Quartz- monzonite porphyry body bellow granodiorite body in this area.
