Abstract

The report provides new data on the mineralogy of ores of the Sharom copper ore occurrence, the Kirganik–Sharom ore zone in Central Kamchatka. Copper ores are confined to the central part of the submeridional massif of subalkaline metasomatites. Mineralization is disseminated, less often vein-disseminated in nature.The studied ore samples, collected during field works in 2023, are represented by silicified metasomatites with developed sulfide mineralization. Among the vein and accessory minerals are quartz, chlorite, barite, and apatite. Ore minerals are represented by magnetite, chalcopyrite, and bornite. Hematite and malachite are the most common supergene minerals, while cuprite and Fe and Cu hydroxides are less common. The established chalcopyrite–bornite mineral assemblage of the Sharom ore occurrence is considered typical of other copper mineral prospects in Central Kamchatka and is characteristic of copper–porphyry deposits.
