About BaratoviteHide

Rauf B. Baratov

Formula:

KCa₇(Ti,Zr)₂Li₃Si₁₂O₃₆F₂

Colour:

White, colorles, pink

Lustre:

Vitreous, Pearly

Hardness:

5 - 6

Specific Gravity:

2.92

Crystal System:

Monoclinic

Name:

Named in honor of Rauf Baratovich Baratov (Рауф Баратович Баратов) (10 October 1921, Pulatan, Turkestan (now Tajikistan) - 15 January 2013, Kazan, Russia), petrologist, Institute of Geology, Dushanbe, Tajikistan.

Type Locality:

ⓘ Dara-i-Pioz Massif, Districts of Republican Subordination, Tajikistan

Note: Some mineralogists consider baratovite to be OH-dominant, which would make katayamalite the same species, with the name baratovite having priority.

The Ti analogue of Aleksandrovite.
