Abstract

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.
