Ringwoodite
Ringwoodite is a mineral with the chemical formula silicon magnesium oxide, SiMg2O4. It crystallizes in the cubic crystal system and belongs to the space group Fd-3m. Classified as a tectosilicate in the Strunz system (9.AC.15) and in the Dana classification as 51.3.3.1, ringwoodite is a high-pressure polymorph of olivine. It exhibits a glassy to subadamantine luster and typically appears green to brown in color. With a hardness of approximately 6.5 to 7.5 on the Mohs scale and a density of around 3.9 to 4.1 g/cm³, it is a key mineral in understanding the Earth's mantle.

Overview
Ringwoodite is a mineral with the chemical formula silicon magnesium oxide, SiMg2O4. It crystallizes in the cubic crystal system and belongs to the space group Fd-3m. Classified as a tectosilicate in the Strunz system (9.AC.15) and in the Dana classification as 51.3.3.1, ringwoodite is a high-pressure polymorph of olivine. It exhibits a glassy to subadamantine luster and typically appears green to brown in color. With a hardness of approximately 6.5 to 7.5 on the Mohs scale and a density of around 3.9 to 4.1 g/cm³, it is a key mineral in understanding the Earth's mantle.
Etymology
Ringwoodite is named after Ted Ringwood, an Australian mineral physicist who made significant contributions to the study of high-pressure minerals. It was first approved by the International Mineralogical Association (IMA) in 1969.
Geological genesis
As a high-pressure polymorph of olivine, ringwoodite forms under extreme conditions in the Earth's upper mantle, typically at depths between 410 and 660 kilometers. It is associated with the transformation of minerals under high pressure and temperature, making it a key mineral in mantle geochemistry.
