Natural History - Diogenite NWA 5480 Meteorite Slice
FOUND 2008 A.D.
1 7/8 in. (3 7/8 x 3 in.) (11.7 grams, 48 mm (58 grams total, 99 x 75 including case)).
A cut slice of scarce achondrite from the diogenite group recorded as: Northwest Africa 5480; displayed in a Swiss membrane box. [No Reserve]
ProvenanceFrom 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.
