Natural Resources of Azerbaijan composed of pyrite and chalcopyrite. Copper-porphyry formations’ ores consist of molybdenum and small amount of noble metals. There are many copper-porphyry formation’s ore in this region except Garadagh and Xarxar deposits (Gedebey ore region). There are copper-porphyte in the Mehmana ore-bearing region (Demirli and Xançincay). Copper-porphyry ore-bearing in the Nakhchivan Autonomous Republic, is mainly located on the Mehri-Ordubad granitoid batholite's exo and endocontact zones (Diakhchay, Goygol, Goydagh etc.). In addition, Halhal copper-pyrite, Goygol, Agridağ copper, Nashirvaz, Kilit-Katam copper-cobalt, Nergirvaz copper-polymetallic are known in this region. Molybdenum field are found in Dalidagh (Teymuruchandagh, Baghırsag, etc.) and Ordubad ore regions (Paraghachay Diachchay).
Volcanogenic massive sulfide ore deposit sulfide consists of over 90% iron sulfide, mainly in the form of pyrite, with chalcopyrite, sphalerite and galena also being major constituents. Magnetite is present in minor amounts; as magnetite content increases, the ores grade into massive oxide deposits. The gangue (the uneconomic waste material) is mainly quartz and pyrite or pyrrhotite. Due to the high density of the deposits some have marked gravity anomalies (Neves-Corvo, Portugal) which is of use in exploration. Alteration haloes developed by VMS deposits are typically conical in shape, occur mostly stratigraphically below the original fluid flow location (not necessarily the ore itself), and are
