flaierite

Flaierite is a rare mineral species, first discovered in 1969. It is named after the German mineralogist and geologist Hans Flaier. Flaierite is a member of the olivine group, which also includes forsterite and fayalite. It is a magnesium iron silicate with the chemical formula (Mg,Fe)2SiO4.

The mineral typically occurs in metamorphic rocks, often associated with other olivine-group minerals and serpentine. It forms under conditions of high temperature and pressure, characteristic of regional metamorphism. Flaierite is usually found in schists, gneisses, and amphibolites.

The mineral exhibits a vitreous to adamantine luster and a white to light brown color. It has a Mohs hardness of 6.5 to 7 and a specific gravity of approximately 3.4 to 3.5. Flaierite is not typically used in industry due to its rarity and the availability of more common olivine-group minerals. However, it is of interest to mineral collectors and researchers due to its unique properties and association with specific geological settings.

Flaierite is not found in significant deposits and is primarily known from a few locations worldwide, including the type locality in the Harz Mountains of Germany, and other areas in Europe and North America. Its occurrence is often limited to specific metamorphic terrains, making it a rare and sought-after mineral among mineralogists.
