Rare minerals of noble metals in the collection of the Mining Museum: new data

Modern analytical methods (optical and electron microscopy, X-ray microanalysis) were used to study the unique samples of sulfide ores from Norilsk ore field Mining Museum collections Saint Petersburg University. Samples containing rare minerals silver platinum-group metals (sobolevskite, urvantsevite, sperrylite, argentopentlandite, froodite, kotulskite, others) studied. The chemical composition, grain sizes, aggregates, mineral associations more than ten noble metal have been refined. efficiency combining various microscopy microanalysis for studying this type is shown. results work made it possible obtain high-quality images minerals, detail information on museum objects, compile their scientific description. conducted research showed relevance objects known deposits complex genesis composition in order find describe with minerals.
