Meteorite | Diogenite NWA 7831 | Asteroidal achondrite | 79g
Product detailed description
We would have to go back one to two billion years to create this meteorite. That's when one of the largest asteroids in the solar system, Vesta (525 km across), was hit by two large meteorites that catapulted chunks of rock into space. These fragments gradually made their way to our planet as meteorites. Vesta is located in the asteroid belt between Jupiter and Mars, and the Dawn spacecraft, after a detailed study of the asteroid, confirmed that its composition exactly matches that of NWA (Northwest Africa) 7831. It is composed mainly of pyroxene crystals, olivine and plagioclase, and its thin sections are beautifully translucent.
The Vesta meteorites belong to the so-called HED meteorites (a subgroup of achondrites), and are subdivided into Howardites, Eucrites and Diogenites - the latter being the most visually beautiful of this group.
Meteorite NWA 7831 was found in March 2013 in the Western Sahara (Sakia al-Hamra) in a relatively small quantity of about 20 kg.
