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.
Two vladimirivanovite varieties (or, possibly, two different related mineral species) can be distinguished. One of them, presumably crystallized at a relatively high temperature, has the simplified formula (Na+6.0–6.4Ca2+1.5–1.7)(Al6Si6O24)(SO42−,S3•−)1.7–1.9(CO2)0–0.1·H2O and has a deep blue color, whereas another one, with the simplified formula (Na+6.2Ca2+1.6)(Al6Si6O24)(SO42−,S4)1.6(CO2)0.1·nH2O (n > 2), is lilac and has low-temperature origin.
Three single-crystal samples studied in this work have similar commensurately modulated orthorhombic structures, with the unit-cell parameter c equal to the triple period of the basic lattice (c = 3c0), unlike triclinic slyudyankaite, with c = 2c0, and the monoclinic analog of lazurite, with c ≈ 21/3·c0. The decrease in symmetry compared to the basic cubic structure of the sodalite type is associated with the ordering of extra-framework components and the regular alternation of hosting sodalite cages of different sizes. With increasing temperature, the degree of structural order of vladimirivanovite gradually decreases until the complete disorder of the extra-framework components and the transformation of the orthorhombic unit cell into a cubic one.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
