Cassiterite crystals from the Atlyansky placers in the Urals

Abstract

Crystal identification tables showed that five crystals of the mining museum N 110/1-4 and 110/8, which were stored as rutile, do not differ from cassiterite crystals. It is also known that these cassiterite crystals were formed from the Atlyan placers of the Southern Urals. When examining the Eremeevskaya collection of the Mining Museum, cassiterite was also discovered in stealth from the Atlyansky placers. Since tin deposits in the central regions of the USSR have not yet been discovered, and geological equipment in the area of the Atlyan River is favorable for the formation of cassiterite deposits, it is necessary to deploy it.
