Golden nugget “Kazanenko”

The results of mineralogical and geochemical studies of a nominal golden nugget from the Central Aldan ore region: morphology, crystalline and nanostructure, xenomineral impurities, chemical composition, trace elements, gas-liquid inclusions, are discussed. Based on the totality of the results obtained, it was concluded that the most likely place for the formation of the golden nugget «Kazanenko» was a rather mature oxidation zone (weathering crust) of the Eocene- Oligocene age at the endogenous gold-low-sulfide- quartz deposit. In the NeoPleistocene-Holocene, the nugget moved to the river placer, where it acquired a refinement border.
