Abstract
The article comprehensively describes host rocks and ores of the Srednekanskaya Dike gold deposit. Ore formation was found to include several stages: metamorphogenic, hydrothermal-metasomatic (productive), and hypergenic. Characteristic features of gold mineralization have been revealed. The bulk of the gold is confined to vein quartz (1); gold fills interstitia in quartz, arsenopyrite, and pyrite (2); in quartz veins and quartz-carbonate-feldspar breccias, localized in microdiorites, gold is deposited in arsenopyrite and pyrite, and associated with diorite-porphyry - only in arsenopyrite (3); the decisive role in the formation of gold mineralization is played by structural control expressed by brecciation and hydrothermal metasomatosis of rocks and by resulting gold sedimentation in weakened zones (4).
