Tephroite

Mn22SiO4
Orthorhombic heart IMA grandfathered

Tephroite is a manganese silicate mineral with the chemical formula manganese(II) disilicate, Mn^2⁺2SiO4. It crystallizes in the orthorhombic crystal system and belongs to the olivine group of minerals. Tephroite has a Mohs hardness of 6 and a moderate density. It exhibits a vitreous luster and is typically light green to yellowish in color. The mineral is classified under the Strunz system as 9.AC.05 and under the Dana system as 51.3.1.4. As a nesosilicate, it is part of the broader silicate mineral classification.

Overview

Tephroite is a manganese silicate mineral with the chemical formula manganese(II) disilicate, Mn^2⁺2SiO4. It crystallizes in the orthorhombic crystal system and belongs to the olivine group of minerals. Tephroite has a Mohs hardness of 6 and a moderate density. It exhibits a vitreous luster and is typically light green to yellowish in color. The mineral is classified under the Strunz system as 9.AC.05 and under the Dana system as 51.3.1.4. As a nesosilicate, it is part of the broader silicate mineral classification.

Etymology

Tephroite is named after its color, which is a characteristic feature of the mineral.

Geological genesis

As a nesosilicate of the olivine group, tephroite typically forms in igneous environments, particularly in mafic and ultramafic rocks where manganese-rich conditions are present.
