Writeup

Writeup from MB 111:

Northwest Africa 14806 (NWA 14806)

(Northwest Africa)

Find: 2021 Sep

Classification: Carbonaceous chondrite (CO3)

Petrography: (J. Gattacceca, CEREGE) Chondrules with average chondrule apparent diameter 230±100 µm (n=38), and small CAIs set in a fine grained iron-rich matrixOpaque minerals are Fe,Ni metal and troilite.

Geochemistry: Olivine Fa_27.0±20.0, range Fa_1.3-69.9, Fa PMD 60% (n=14). Cr₂O₃ in ferroan olivine 0.28±0.12 (n=12). Low-Ca pyroxene Fs_2.7±0.6Wo_0.9±0.6(n=5), Fs_52.5Wo_1.7(n=1). Ca-pyroxene Fs_1.9Wo_44.7(n=1).

Classification: Carbonaceous chondrite (CO3). Fa range and Cr₂O₃ content of ferroan olivine suggest a low petrographic subtype.

Specimens: Type specimen at CEREGE. Main mass with Laurent Lodé.
