Northwest Africa 2269

Found 2002 March

Carbonaceous chondrite (CV3)

The meteorite, found by Nomads near Tindouf (southwest Algeria) weighs 184 g and is completely covered by a fusion crust. Mineralogy and the classification (A. Seddiki, UO/UJM, B. Moine, J.Y. Cottin, UJM; M. Denise, MNHNP). Chondrules are less than 2 mm in diameter and are poorly abundant (<20%). CAIs (Anorthite, Spinel and melilite) are different sizes and up to 1cm. The fine-grained matrix is very abundant. Chondrules consist of non-equilibrated porphyric olivine (Fa0.7-Fa28), or Opx (Fs0.91), glass, magnetite, pentlandite and a few rare spherules of iron metal in the olivine crystals. Anorthite occurs in the center part of some opx chondrules (An85 Ab16), associated to the fassaïte (Fs08 Wo44) and hedenbergite (Fs42 Wo50).  In the matrix the olivine is Fa55-91. Specimens: type specimen, 23.6 g, MNHNP; plus 4 g and thin sections, UJM, main mass with finders.
