Chemical composition and varieties of sulfosalts from gold mineralization in the Gaching ore occurrence (Maletoyvayam ore field)
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 (...

| Summary: | 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. |
