Natural History - Diogenite NWA 5480 Meteorite Slice
Found 2008 A.D.Sold for (Inc. bp): £52
A cut slice of scarce achondrite from the diogenite group recorded as: Northwest Africa 5480; displayed in a Swiss membrane box. 11.7 grams, 48 mm (58 grams total, 99 x 75 including case)
From the Sahara, N.W. Africa. Ex Hupe collection, U.S.A. From a Leicestershire, UK, collection.
The total known mass of the meteorite found in Mali was 4.91 kg. Mineralogically, the diogenites are primarily composed of magnesium-rich orthopyroxene, with minor amounts of plagioclase and olivine. The pyroxenes are usually coarse-grained, suggesting a cumulate origin for the diogenites in magma chambers within the deeper regions of Vesta's crust. The achondrites of this group are named after a 5th century B.C. Greek philosopher Diogenes of Apollonia, who was the first to suggest that meteorites originate from outer space.
