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 sulfidic sediments, similar to SEDEX ores, and is generally manganese, barium and hematite enriched, with cherts, jaspers and chemical sediments common. Most VMS deposits show metal zonation, caused by the changing physical and chemical environments of the circulating hydrothermal fluid. Ideally, this forms a core of massive pyrite and chalcopyrite around the throat of the vent system, with a halo of chalcopyrite-sphalerite-pyrite grading into a distal sphalerite-galena and galena-manganese and finally a chert-manganese-hematite facies. Most VMS deposits show a vertical zonation of gold, with the cooler upper portions generally more enriched in gold and silver. The mineralogy of VMS massive
