Abstract

Abstract The Gaching ore occurrence within the Maletoyvayam ore field is located in the southwestern part of Kamchatka volcanic belt. The ore occurrence belongs to high-sulfidation epithermal type. The sulfosalts of the fahlore-group (tennantite, tetrahedrites and goldfieldite) and enargite-groups (enargite, luzonite, famatinite) found in the gold mineralization of the Gaching ore occurrence. The presence of Cu-rich and Se-bearing fahlores as well as enargite-group sulfosalts in ores indicate a high oxygen volatility at temperature less than 250º during their formation.
