About GazeeviteHide

Formula:
BaCa6(SiO4)2(SO4)2O
Colour:
Colourless
Lustre:
Vitreous
Hardness:
Specific Gravity:
3.39 (Calculated)
Crystal System:
Trigonal
Name:
In honor of Dr. Viktor Magalimovich Gazeev (b. 1954), research staff-member of Institute of Geology of Ore Deposits, Petrography, Mineralogy and Geochemistry Russian Academy of Sciences (IGEM RAS), Moscow and of Vladikavkaz Scientific Center of the Russian Academy of Sciences, Vladikavkaz, Republic of North Ossetia-Alania, Russia. He is the discoverer of unique xenoliths within the Upper Chegem Caldera (Gazeev et al., 2006), where more than 20 new mineral species were discovered, co-authored by him.
Isostructural with:
One of a few Ba-Ca silicate-sulfate minerals, especially similar to dargaite and somewhat to wenkite. Structurally related to nabimusaite group (e.g., zadovite).

The structure is of modular-layered type, derived from that of hatrurite. More specifically, it has single (broken) antiperovskite layers [WB6](TO4)2 and is of gazeevite-zadovite type.
