Formula: Fe₂SiO₄ [it could be written Fe²⁺₄O(Si₂O₇) to better reflect the structure]
Sorosilicate (Si₂O₇ groups), high-pressure orthorhombic paramorph of isometric ahrensite and fayalite, which is also orthorhombic
Crystal System: Orthorhombic

Meteorites

Asimowite is a relatively new mineral, approved in 2018.

Localities

At the type locality, the Suizhou meteorite, Xihe, Zengdu District, Suizhou, Hubei, China, asimowite was discovered in rare shock-melted silicate droplets, and also in the Quebrada Chimborazo chondrite, Antofasto, Chile. Asimowite is rare, but the shock-melted silicate droplets are very frequent in both meteorites, and most of them contain iron-rich wadsleyite (AM 104.5.775-778). Other Associated minerals include fayalite and an iron - nickel metal (likely taenite) (HOM).
