NWA 5000

Northwest Africa 5000 (NWA 5000) is a lunar (feldspathic breccia) found in southern Morocco in July of 2007.

According to the Meteoritical Bulletin (MB 93), NWA 5000 is:

A single, large cuboidal stone (11.528 kg) with approximate dimensions 27 cm × 24 cm × 20 cm. One side (which appears to have been embedded downward in light brown mud) has preserved regmaglypts and is partially covered by translucent, pale greenish fusion crust with fine contraction cracks. Abundant large beige to white, coarse-grained clasts up to 8 cm across (some of which have been eroded out on exterior surfaces of the stone, likely by eolian sand blasting) and sparse black, vitreous clasts up to 2 cm across (containing irregular small white inclusions) are set in a dark gray to black, partially glassy breccia matrix. One partially eroded clast exposed on an exterior surface contains both the coarse grained beige lithology and the more resistant black, vitreous lithology in sharp contact.

Just over 11.5 kg (25.4 lb) of NWA 5000 have been recovered.
