Writeup

Writeup from MB 110:

Northwest Africa 14097 (NWA 14097)

(Northwest Africa)

Purchased: 2021 Apr

Classification: Carbonaceous chondrite (CM2)

Physical characteristics: Small sub-cm dark fragments.

Petrography: (J. Gattacceca, CEREGE) Chondrite with small chondrules (average apparent diameter 290±160 µm, n=25) set in a abundant fine-grained iron-rich matrix (72 vol% by point counting, n=265). Opaque minerals are sulfides, magnetite and rare metal.

Geochemistry: Olivine Fa_12.3±18.9, range Fa_1.4-44.9(n=4). Low-Ca pyroxene Fs_1.5Wo_2.8(n=2). Defocused eletron microprobe analyses of the matrix give analytical totals of 79.5 wt% and FeO 33.7 wt%.

Classification: Carbonaceous chondrite (CM2). The low analytical totals in the matrix indicate the presence of hydrous phases.

Specimens: Type specimen at CEREGE. Main mass with Kuntz
