Baratovite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
KCa7(Ti,Zr)2Li3Si12O36F2
Colour:
White
Lustre:
Pearly
Hardness:
Crystal System:
Monoclinic
Name:
Named in honor of Rauf Baratovich Baratov (1921{ ), Soviet petrologist, Institute of Geology, Dushanbe, 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.
