Mesosiderites formed during ancient asteroid collisions that mixed crustal rock with metallic core material

specifically a polymict eucrite

and iron-nickel metal phases such as kamacite and taenite

Composition: Olivine-rich (~70–80%)

and absence of visible chondrules distinguish it from lower-grade H-type meteorites
