Monoclinic root IMA redefined

Magnesio-riebeckite is a monoclinic amphibole mineral with the chemical formula ☐Na2(Mg3Fe^3⁺2)Si8O22(OH)2. It is a member of the riebeckite group, characterized by its chain silicate structure. The mineral typically exhibits a prismatic crystal habit and a vitreous to pearly luster. It is usually dark green to black in color and has a Mohs hardness of 6. With a relatively high density, it is commonly found in metamorphic and igneous environments. Magnesio-riebeckite is classified under the Strunz system as 9.DE.25, indicating its position among inosilicates.

Overview

Magnesio-riebeckite is a monoclinic amphibole mineral with the chemical formula ☐Na2(Mg3Fe^3⁺2)Si8O22(OH)2. It is a member of the riebeckite group, characterized by its chain silicate structure.

Etymology

The name magnesio-riebeckite is derived from the high magnesium content in its chemical composition. It is a variant of riebeckite, with magnesium substituting for iron in the structure.

How to recognize it

Magnesio-riebeckite can be identified by its Mohs hardness of 6, dark green to black color, and vitreous to pearly luster. It often forms prismatic crystals and may show a white or light-colored streak. Its monoclinic crystal system and inosilicate classification help distinguish it from other amphiboles. It is commonly confused with similar amphibole species due to overlapping physical properties.

Host rocks

Magnesio-riebeckite is typically found in metamorphic and igneous rocks, particularly those with high magnesium content. It may occur in environments where amphibole minerals are stable, such as in certain types of gneiss or schist.
