Oued Namous 001 Angrite Individual Meteorite with Crust 11.8g

Angrites are a rare group of achondrites consisting mostly of Al-Ti bearing diopside, hedenbergite, olivine, anorthite and troilite with minor traces of phosphate and metals. The group is named for the Angra dos Reis meteorite. They are the oldest igneous rocks, with crystallization ages of around 4.56 billion years. Angrites are subdivided into two main groups, the quenched and plutonic angrites. The quenched angrites cooled rapidly upon the surface of the angrite parent body (APB), whereas the plutonic angrites cooled slower, deeper in the crust. The APB is thought to have been a similar size to the asteroid 4 Vesta.

This meteorite was found approximately 15 km east of a major dry riverbed Wadi Al-Namous (aka Oued Namous) and approximately 10 km north of highway N6B in El Bayadh Province, Algeria, in May 2021.  This was classified by Dr. Carl Agee from the University of New Mexico.  It was classified as a volcanic angrite based on the significant igneous zoning of olivine and pyroxene.  There is only 1402 grams of this material known to exist. 

The weight of this piece is 11.8 grams.
