Dykes of the Kadjaran copper-molybdenum deposits and ore field

Within the ore field, several rhythms of manifestation of porphyry magmatism are distinguished. The same type of porphyry dikes and the spessartites preceding them are concentrated mainly in structural-tectonic belts of different ages - the late Oligocene Vokhchinsky and Lernadzor, and the late Oligocene-Miocene Bagajur and Medvezhye. In certain segments of the Vokhchin and Lernadzor zones, in accordance with the tectonic situation, the ores of the deposit and ore occurrences are localized. The intersection of the porphyries of these zones with kersantites, which, in turn, are cut by ore bodies, has been established. A number of isotope-geochemical parameters indicate a significant contribution of the mantle substrate to the porphyry ore system, and the close conjugation and sequence of intrusion of dikes and ore bodies indicates that not only porphyries, but also lamprophyres are derivatives of a single fluid-porphyry system
