The article presents a study on lazurite's crystallographic structural transformation from the Baikal region. It says that one of the most difficult problems related to lazurite is the issue of existence of cubic incommensurate 3D-modulated structure (I3DM). It mentions that two lazurite samples were studied to explore its structural instability such as the cubic with I3DM from the Pokhabikha deposit and the rhombic from the Tultui deposit. It mentions several methods were used in the study including X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and thermoanalysis (TA). Results show that the I3DM-structure in cubic lazurite from the Baikal region has a growth origin, although it is not a metastable state at incomplete polymorphic transformation.
