Tatarinovite is a relatively new mineral, approved in 2015.

Localities

At the type locality, the Western wall, Southern open pit, Bazhenovsk deposit, Asbest, Sverdlovsk Oblast, Russia, tatarinovite occurs as colourless, bipyramidal crystals up to 1 mm across in cavities within massive diopside, and as white granular aggregates up to 5 mm in size on grossular, in cavities in a rodingite body at the contact between a dike of partly rodingitised gabbroic rock and hosting serpentinite. Associated minerals include diopside, xonotlite, clinochlore, pectolite and calcite (HOM, Mindat).
