This is a cut and polished section of a carbonaceous chondrite. This is one of the oldest, and most primitive of all meteorites. The cutting and polishing makes the colourful chondrules more defined allowing you to clearly see them in these samples.
These meteorites are the same type as the Sahara chondrite meteorite and the cut and polished Sahara chondrite meteorites in the loan box, except that they have been cut to a smaller size and polished to expose the chondrules inside so that you can see them in more detail. The chondrules are rounded mineral grains and vary in colour.
These meteorites were discovered in the Sahara desert and are part of a huge strewn field (the area over which fragments of a larger meteorite have fallen). Meteorites from this region are often named with the designation “NWA” which stands for North West Africa. The small samples in the loan box are classified as NWA 7454.
The samples in the loan box are supplied encased in a membrane box for display and to protect the sample – please do not try to open this box.
