Dzhalindite
A rare indium hydroxide described in 1963 from the Dzhalinda tin deposit in Russia's Far East.
Intro adapted from Wikipedia (CC BY-SA).
Dzhalindite is an IMA-recognized mineral species in the oxides & hydroxide class, with the chemical formula In(OH)₃.
It crystallizes in the cubic crystal system (space group Im3). It is a member of the Perovskite structural group.
Key properties: specific gravity 4.38.
IMA symbol Dz, IMA status: approved, named in 1963.
Probably of secondary origin from its occurrence along fractures through primary hydrothermal minerals in association with brecciated felsic volcanic rocks (Dzhalinda deposit, Russia); in sulfides hosted in greisenized granite (Mangabeira.
It is found associated with Indite, cassiterite, quartz (Dzhalinda deposit, Russia); sphalerite, galena, chalcopyrite, stannite, calcite, quartz (Mount Pleasant, Canada); roquesite.
The name refers to the occurrence in the Dzhalinda tin deposit, Russia.
