Ureilite The section is an aggregate of olivine and pyroxene (up to ~3 mm) with dark interstitial materials. Olivine grains have dark rims (200-500 μm thick) due to the presence of minute opaque minerals (Fe metal and troilite). Elongated graphites (hundreds μm long and several tens μm thick) occur sparsely. Compositions of olivine are Fa1.7-21.5. | ||||||||||||||||||
