Northwest Africa 869 History

Name: Northwest Africa 869
Location: near Tindouf in Algeria
Type: Ordinary Chondrite, Brecciated L5

The meteorite was discovered in 1999 near Tindouf in Algeria and it is estimated that around1500kg of stones have been found, making it one of the largest Total Known Weight stone meteorites to come out of North West Africa. It is a very attractive looking meteorite and has a number of distinguishing features. When cut and polished, the matrix is full of colour and chondrules. It is also possible that it may contain carbonaceous inclusions and be brecciated. The stones of this meteorite vary quite widely which makes classification difficult. Some individuals will show the dark inclusions and brecciation, while others will not even hint at it. This meteorite has been classified a numerous times by different institutions around the world and they have all come up with a different classification. One thing they all agree on however, is that it's an L-Chondrite! UCLA originally classified NWA 869 as L4, but later reclassified it to L5, which stands as it's current official classifiaction. It has also been classified as L3.9-6 and L6. A couple of these classifiactions have also said it is brecciated. Well whatever the classification, one thing remains true: it's a great looking meteorite!

This meteorite was published in the Meteoritical Society Bulletin No. 90
