DESCRIPTION:
NWA8576, the second ever LL3.00 to be classified in the world. When you talk about rare meteorites, this NWA is near the top of the list in rarities. Few grams were classified from one single stone. After the 20% donation and cutting losses, there is very very limited specimens available for acquisition.

This specimen is associated (paired) with the same fall of NWA 8576

Guaranteed by the Geologist Juan Avilés Poblador

Classification: Ordinary chondrite (LL3.00)

History: Purchased by Brahim Tahiri from a Moroccan hunter in Erfoud, Morocco and sent to his partner Sean Tutorow for classification.

Classification: Optical microscopy shows that this meteorite has ferroan olivine grains with no chromite exsolution; this implies it is outside the 3.05-3.15 range. About 10 different porphyritic chondrules in the thin section were examined. The meteorite cannot be type 3.2 or higher since it has such high Cr in the ferroan olivine and a low standard deviation similar to Semarkona (LL3.00), Grossman and Brearley (2005). The chondrules average about 600 μm in diameter, consistent with an LL classification.

A physical certificate of authenticity is provided free of charge with every meteorite we sell. This is our lifetime guarantee.
