James writes:
NWA 4561 is one of the 20 or so meteorites that are very ancient and often referred to as Paleo Meteorites. Classification of these meteorites has been a challenge as they are quite altered and chondrules in some pieces are few and scattered or missing. But regardless of what some of the older original classifications were for this group of stones they are Enstatite Chondrites. The specimen shown has the interesting blue color that some of these ancient meteorites have developed.
