# NASA data for LAR 06618 Weathering: Ce Fracturing: C Fa: 19-7 mol %
Thick black vesicular fusion crust covers 30% of the exterior of this meteorite. The surface has slightly platy fracturing. The rusty brown interior is coarse grained with minor evaporates in tiny spots.
The section consists of an aggregate of large (up to 2.5 mm) olivine grains. Individual olivine grains are rimmed by carbon-rich material containing traces of metal. Metal forms veins between olivines. Olivine has cores of Fa₉, with rims reduced to Fa₇. The meteorite is a ureilite.
