Unclassified NWA meteorite_88.5 grams

            An unclassified Northwest Africa meteorite, (NWA XXX) weighing 88.5 grams.

(For scale, the black cube has sides of 1 cm).

The meteorite's shape appears somewhat oriented, so it probably maintained a fairly stable attitude during at least part of its fall through the atmosphere.

Its surface has been smoothed over time by exposure to the abrasive effects of wind-blown sand in the desert, but nevertheless, the convex face shown in this image - (probably the trailing side during stable atmospheric flight) - still retains some contraction cracks in remnant fusion crust. Contraction cracks in the fusion crust are the result of cooling during the final cold, dark part of atmospheric flight.
