About VolkovskiteHide

Formula:
KCa4[B5O8OH]4[B(OH)3]2Cl · 4H2O
Colour:
Colourless, pink; varying from pale to deep orange
Lustre:
Vitreous
Hardness:
Crystal System:
Triclinic
Name:
Named in honor of A.I. Volkovskaya (А.И. Волковской), Russian petrographer who first found the mineral in water insoluble residues from drill cores.

Volkovskite was first described from Kazakhstan [TL1] by Kondrat’eva et al. (1966), and redefined by Mandarino et al. (1990) from the Salt Spring deposit [TL2]. The redefinition established the triclinic symmetry and presence of K and Cl as essential constituents in the mineral.
Structurally related to Veatchite.
