NWA 8118, Primitive Achondrite Lodranite, Micromount


Lodranites are related to acapulcoites and have an affinity to H chondrites. It is believed they represent a chondritic parent body which experienced extensive melting to the point where it's elemental composition was completely altered beyond recognition. They are one of rarest petrologic types of meteorite, with only 63 known and classified. They are made primarily of silicates and this example is mostly clinopyroxene with greenish crystals set into a semi-oxidized groundmass. This meteorite was recovered out of the Sahara in Morocco in 2013. It was classified at UWS by Dr. Tony Irving. After cutting and classification, there was less than ~900 grams available for collectors.
