It occurs as red to orange brown cubic crystals and crystal masses. It is a member of the perovskite group. It was first described in 1982 for an occurrence in a syenite intrusive in Tausonite Hill, Murunskii Massif, Aldan Shield, Sakha Republic, Yakutia, Eastern-Siberian Region, Russia.[1] It was named for Russian geochemist Lev Vladimirovich Tauson (1917–1989).[3] It has also been reported from a fenite dike associated with a carbonatite complex in Sarambi, Concepción Department, Paraguay.[2] and in high pressure metamorphic rocks along the Kotaki River area of Honshu Island, Japan.[1] References1. ^1 2 Tausonite on Mindat.org 2. ^1 Tausonite in the Handbook of Mineralogy 3. ^1 Tausonite data on Webmineral 4 : Oxide minerals|Titanium minerals|Strontium minerals|Cubic minerals |
