Typomorphic features of placer gold from alluvial deposits of the Bolshaya Kuonamka river basin, draining Eastern framing of the Anabar massif are studied in order to identify association types of primary sources and places, promising for their discovery.
Based on identified indicators of gold, it is defined that, ore manifestations of low-sulfide gold-quartz association are the main primary sources of gold-bearing placers. Identification of palladium gold in association with platinoids, as well as its intergrowth with ferruginous platinum indicates origination of manifestations of gold-platinum ore association. In addition, primary sources of gold rare-metal association type are forecasted, based on discovery of inclusions of native bismuth, maldonite and hessite in gold. Disseminated ore mineralization is discovered for the first time, which is localized in a tectonic fault zone of the Cambrian carbonate rocks of Eastern framing of the Anabar massif. Mineralization is represented by finest precipitations (from first mkm) of native gold and silver, pyrite, antimonite, molybdenite, arsenopyrite and faded ore. It is supposed that, ore manifestations of this type could be one of the primary source of very fine particles gold of the Bolshaya Kuonamke river basin. |
