Zabuyelite

Zabuyelite is the natural mineral form of Lithium carbonate, formula Li2CO3. Discovered in 1987 at Zabuye Salt lake, Tibet, after which it is named. It forms colourless vitreous  monoclinic crystals. Such is the solubility of Lithium carbonate that it is unlikely to occur naturally anywhere except in Evaporites and arid conditions.
