NWA 16454 : Polymict Ureilite

Breccia with mineral clasts up to mm. The few lithic clasts show an equilibrated texture with poikilitic texture.

​

Aggregates of carbon material (likely diamond in view of the extreme difficulty to cut and polish the meteorite) reach 1 mm in size and display geometric shapes. C1-like clasts to 500 µm are present.
