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).
Metal detector in the chest of American President James Garfield in 1881; the metal detector worked correctly but the attempt was unsuccessful because the metal coil spring bed Garfield was lying on confused the detector. The modern development of the metal detector began in the 1920s. Gerhard Fischer had developed a system of radio direction-finding, which was to be used for accurate navigation. The system worked extremely well, but Fischer noticed there were anomalies in areas where the terrain contained ore-bearing rocks. He reasoned that if a radio beam could be distorted by metal, then it should be possible to design a
