UDC 553.41:(550.84+550.93)(571.1) EPITHERMAL GOLD-SILVER MINERALIZATION OF THE KABURCHAK ORE CLUSTER (MOUNTAIN SHORIA) – DISTRIBUTION FEATURES, MINERALOGY AND AGE
A. I. Chernykh, P. A. Nevolko, A. S. Borisenko
The Kaburchak gold-silver cluster, one of the most promising for gold-silver mineralization within the Altai-Sayany folded region, is characterized in the article. For the first time for this type of mineralization the 40Ar/39Ar isotope-geochronological data have been obtained from the gold-bearing beresites. The age of the Kalarskoye field gold-silver mineralization has been defined to be 396.2±3.8 million years. New data on mineralogical composition of the gold-silver ores are given, including those obtained by means of an electronic microscope. The gold-silver mineralization of the Kaburchak cluster was estimated as very promising based on analysis of previous and new geological, geochemical, and mineralogical data and on comparison with data on the Novofi rsovskoye deposit.
Key words: gold, silver, Altai-Sayany region, mineralization, age.
