kivimiteMg
KivimiteMg is a proposed magnesium-rich silicate mineral described as an end-member within the pyroxene group. The name points to magnesium as the principal cation, with iron capable of substituting in smaller amounts. In theoretical terms, its simplified formula is written as (Mg,Fe)SiO3, representing a solid solution between more magnesium-dominant and iron-bearing compositions.
Crystal structure and classification: KivimiteMg is described as an inosilicate with a single-chain silicate framework, crystallizing
Physical properties: In synthetic samples, kivimiteMg is expected to appear as pale to olive-brown or gray-green
Occurrence and formation: No natural specimens have been confirmed to date. In experimental simulations of high-temperature
Etymology: The name combines kivim, a coined term linked to stone, with Mg to indicate magnesium content.
