A stone weighing 192 g was found in the Moroccan Sahara. Northwest Africa 033 is also known as Taouz 003. Classification was done at the Institut für Planetologie, Münster, Germany (main mass with JNMC). This carbonaceous chondrite is unusual in light of its low matrix abundance and nearly equilibrated olivines within the chondrules. It has an O-isotope composition nearly identical to that of Allende and Axtell, with an oxygen three-isotope plot within the CV field. However, it contains less trapped noble gases, having only a cosmogenic component of neon. It has a CRE age of ~20 m.y. Northwest Africa 033 is shocked to stage S2 and is highly weathered to a grade of W3/4. The specimen of NWA 033 shown above is a 5.3 g partial slice with some remnant fusion crust.
