The Vertical Geochemical Zonation of the Tutkhlivayam Ore Occurrence and Criteria for the Assessment of the Erosion Level within the Eruvayam Ore Cluster (Kamchatka)

The vertical geochemical zonation of the Tutkhlivayam epithermal Au–Ag occurrence (Ossora ore district, Kamchatka) is studied. The chemical composition of ores was studied after chip sampling; the concentration coefficients of chemical elements and geochemical associations in horizon-by-horizon samples have been determined. The vertical range of geochemical zonation has been identified (bottom to top): Cd–Pb–Zn–Cu–Ag–Mo–Sb–As–Hg–Fe–Ba–K–Mn–Au–Sr–Ca. The suggested indicators for the assessment of the erosion level of the occurrence are recommended for Au–Ag objects of the Ossora ore district and similar deposits of volcanic belts.
