About Vladimirivanovite
Formula:
Na6Ca2(Al6Si6O24)(SO4,S3,S2,Cl)2 · H2O
Colour:
Dark blue to ink-blue, light blue or greenish-blue to white
Lustre:
Greasy
Hardness:
5 - 5½
Specific Gravity:
2.48
Crystal System:
Orthorhombic
Member of:
Name:
Named in honor of Vladimir Georgievich Ivanov (Владимир Георгиевич Иванов) (1947-2002), Russian mineralogist and geochemist. He studied the lazurite deposits of the Pamirs and Pribaikalye and made significant contributions to the knowledge of the complex processes of lapis formation.
First recognized as “triclinic lazurite” (compare UM1976-26-SiOSO:AlCaClHNa) and later as “orthorhombic lazurite”; but later as an orthorhombic polytype of lazurite with a modulated structure, i.e. Lazurite-O. The modulations arise from a rotation of the sulfate tetrahedra in the sodalite cages.
Lazurite is itself probably just a sulphide-rich variety of Hauyne, or a hypothetical endmember, and the analysis of Vladimirivanovite (Handbook of Mineralogy) indicates that it is sulphate rich and thus closer to hauyne than lazurite.
