Description

NWA 6926 is an unusual meteorite with a yellow-green crystalline structure. This find was recovered out of the Saharan Desert in 2011. It was classified as an ungrouped achondrite with affinities to the acapulcoite and lodranite clan. This meteorite was quite fresh and composed of crystal matrix. Some regions show fluid bubble structure. Further study revealed that this meteorite originates from an unknown, differentiated parent body and may have some assocation with the CR clan of meteorites.
