EXPERT ESTIMATION OF UNDISCOVERED RESOURCES FOR PORPHYRY COPPER ORE CLUSTER GOLD-POLYMETALLIC MINERALIZATION ALTAI TERRITORY

porphyry copper ore clusters, zoning, gold-polymetallic mineralization resource estimation, Lesser Caucasus, Tethys structure.Abstract
Based on porphyry copper ore clusters formed in Eocene-Miocene and Jurassic-Cretaceous geological development of the Lesser Caucasus and the
western Tethys structure sector, direct correlation is defined between porphyry copper and gold-polyme-tallic mineralization resources as well as «parental» granitoid massif outcrops. The emerging regularity is not contradictory to the established schemes of porphyry copper ore cluster formation showing their
centrifugal zoning in relation to the «parental» granitoid massif and evolutionary replacement of copper-molybdenum mineralization by gold-polymetallic type. Based on this regularity, undiscovered goldpolymetallic mineralization resources express estimation method may be proposed for porphyry copper ore clusters underexplored for gold-polymetallic mineralization
