Brenham

Pallasites like Brenham are mixtures of green olivine crystals and iron-nickel metal. They formed where the olivine-rich mantle mixed with the underlying metal-rich core of a molten asteroid.

Chinguetti

Mesosiderites like Chinguetti are enigmatic rocks formed during collisions on the surface of an asteroid. Chinguetti was originally thought to be a fragment of a meteorite more than 100 meters in length, although modern workers have disproven this.

Esquel

In Esquel, the olivines retain their characteristic crystal shapes, suggesting formation in a tranquil environment.

Imilac

Pallasites are mixtures of green olivine crystals and iron-nickel metal. They formed where the olivine-rich mantle mixed with the underlying metal-rich core of a molten asteroid.

Otinapa

The broken masses in Otinapa may reflect more violent mixing of olivine and metal.
