STAGES OF FORMATION OF GOLD MINERALIZATION SOUTH OMOLONSKY ARRAY

Фомина М.И.
Polychronic mineralization is characterized by Abkitskom and Noddinskom ledges Archean basement Omolonsky array (Magadan Oblast). A comparative analysis was conducted for determinations of gold mineralization associated with tectonomagmatic activation of various epochs – PR2, PZ1, PZ2-3, MZ2, – manifested in this structure. It has been demonstrated: that the Late Proterozoic Age is characterized by deposition of gold within the Riphean gabbroids and ferruginous quartzites. The Early-Paleozoic Epoch is characterized by formation of veins with gold-tellurium-bismuth mineralization. The Middle-Late-Paleozoic Epoch is characterized by formation of quartz-carbonate and quartz-fluorite veins with polysulphidic gold and gold-tellurium mineralization. Gold/silver mineralization is associated with the Late Mesozoic Epoch. At the same time, the spatially converged mineralization demonstrates traces of inheritance of earlier epochs.
