Chondrite North-West Africa

General information about unclassified meteorites:

Many such unclassified meteorites have been found in the desert areas of North Africa. They are called NWA meteorites (North West Africa) and can be of uncertain age on Earth. They have often lain for a while and got a brownish patina on the surface as well as being in different condition. But inside, the petrological content can be just as interesting.
