Tazheranite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Zr,Ti,Ca)O2-x
Ideal formula ZrO2, same as cubic zirconia.
Colour:
Bright orange to red-orange
Lustre:
Adamantine
Hardness:
Crystal System:
Isometric
Name:
Named after its discovery locality, Tazheran (Tazheranskii) alkaline complex, Baikal Alkaline Province, Russia.
Compare also baddeleyite.
According to initial description Ti in Tazheranite is trivalent in difference from Zirkelite.

Possibly the natural form of 'cubic zirconia', although usually greatly impure compared to the synthetic gemstone.

A mineral with the name 'arkelite' was reported as isometric ZrO2 inclusions in zircon crystals. This is now regarded as synonymous with Tazheranite (Burke, 1989)
