Albovite (original) (raw)

Valid as an unnamed mineral

Formula:

Ca2(SiO4) · CaCl2

Colour:

White, blue, greenish, colorless

Crystal System:

Monoclinic

A substance of anthropogenic origin (burning coal mine dump). Current IMA regulations do not allow such substances to be approved as valid mineral species.

Material also found in an altered xenolith of the Shadil-Khokh Volcano, South Ossetia. The crystal structure determination of the phase founded in a natural environment was impossible due to its instability under atmospheric conditions and tiny crystal size. It is known as a metastable phase in Portland cement clinkers.

Weakly hygroscopic.
