NWA 12262 is a medium-grain, olivine-free shergottite. It displays a diabasic texture with some small glassy shock melt pockets. Though grain size may vary between the meteorites it has been suggested that NWA 12262 may be related to several other Martian meteorites which originated from one heterogeneous single meteoroid found at a single location. NWA 12262 has a brownish color with a hint of green remeniscent of olive-drab. Cut slices show a mixture of dark nearly black cystals and dark brown crystals. It is a fantastic meteorite. With only a few hundred pound total of Mars rocks on Earth NWA 12262 is a great opportunity to obtain a sample of the Red Planet.
