Frankamenite : K3Na3Ca5(Si12O30)[F,(OH)]4·H2O, Charoite : (K,Na)5(Ca,Ba,Sr)8(Si6O15)2(Si6O16)(OH,F)·H2O, Aegirine : NaFe3+[Si2O6]
	Magistral'nyi area, Sirenevyi Kamen' Deposit, Murunskii Massif, Chara and Tokko Rivers Confluence, Aldan Shield, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia Apple-green monograins of frankamenite and dark aegirine prismes within lilac fibrous charoite agregate from Magistral'nyi part of the Sirenevyi Kamen' charoite deposit. Such canasite-like variety of the mineral is most abundant on Murun massif, much more than violet-grey or grey variety from Bertil Otter photo. Besides that this violet variety is ...

Tokkoite : K2Ca4Si7O17(O,OH,F)4, Charoite : (K,Na)5(Ca,Ba,Sr)8(Si6O15)2(Si6O16)(OH,F)·H2O
	Magistral'nyi area, Sirenevyi Kamen' Deposit, Murunskii Massif, Chara and Tokko Rivers Confluence, Aldan Shield, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia Rich specimen of orange-brown sun-like agregates of tokkoite with lilac fibrous charoite and very minor black aegirine from the type locality - Magistral'nyi area of Sirenevyi Kamen' charoite deposit. Tokkoite is VERY similar to some sorts of tinaksite, so it is almost impossible to distinguish these two minerals by eye. Only very keen and trained ...
