UDC (553.411:550.42):(552.1+54)(571.513) CARBONIC MATTER IN LARGE-VOLUME NONTRADITIONAL GOLD-ORE OCCURRENCES OF THE FEDOROVKA-MAGYZY-KALTAS ZONE (KUZNETSK ALATAU). PT 1
A. B. Shepel, M. E. Gavrilenko
The paper provides brief geological description of the large-volume non-traditional Kedrovskoye goldore occurrence in the Fedorovsko-Magyzy-Kaltasskaya structural-metallogenic zone. The authors have studied the results of mineragraphic-petrographic, chemical-analytical, chromatographic, and derivative-metric analysis of the carbonic matter tracing ore-controlling tectonic zones in the Kaltasskoye, Kedrovskoye, and other gold-ore occurrences of the Fedorovsko-Magyzy-Kaltasskaya zone. It has been found that the carbonic matter is represented by graphite with maximum exothermal peaks of 920 °С in gold-bearing metasomatites, and those of 680 °С and 720 °С in hosting rocks. The carbonic matter is characterised by low gas reduction ratio (0.006–0.021), which indicates absence of hard bitumen therein.
Key words: carbonic matter, graphitisation, Kedrovskoye gold-ore occurrence, gold-bearing metasomatites and hydrothermalites, Fedorovsko-Magyzy-Kaltasskaya zone, Kuznetsko-Altaysky deep fault.
