Description:
A UNIQUE ACHONDRITE METEORITE - NWA 2993
Winonaite-"Evolved"=A Lodranite Analog from the Winonaite Parent Body (Asteroid)
Found June 2006 in the Algerian Sahara
Total known weight = 625 grams

When first submitted for analysis and classification to Northern Arizona University and The University of Washington, this meteorite created huge excitement among the scientists because its mineralogy and appearance were nearly identical to the famous Lodran from Pakistan, the namesake of an exceptionally rare class of meteorites called Lodranites. Only after oxygen isotope analysis was completed did they realize that they had discovered an entirely new class of meteorites analogous to Lodranites, but sourced from a different asteroid parent body altogether. Lodranites and their cousins, the Acapulcoites (named after Acapulco, Mexico where this type was first witnessed as a fall) are very rare achondrite meteorites which originated on a large chondritic parent body with a unique composition unlike any of the other chondrite groups known. The Acapulcoite-Lodranite parent body was excessively heated causing thermal metamorphism resulting in differentiation and layering. This meteorite, NWA 2993 is the only known member of this new type making it arguably the rarest meteorite ever found!

This gorgeous thin slice of this extremely important meteorite exhibits a large field of reddish, green and black high temperature silicates, primarily orthopyroxene and olivine, with an attractive "leopard-spot" pattern of bright silvery nickel-iron injected into the silicates. It looks almost exactly like Lodran, which is considered to be one of the most beautiful meteorites in the world, but the olivine in Lodran is a lighter green color. The slice measures 22.2 mm by 15.7 mm by 1 mm thick and weighs 1.05 grams. Samples of this meteorite are virtually undistributed to the major museums and universities around the world, as well as to private collectors, leaving an important hole in virtually every collection. An exceptionally rare and scientifically important meteorite specimen.
