Writeup from MB 106:

Northwest Africa 11098 (NWA 11098)

Morocco

Purchased: 2016 Dec

Classification: Ordinary chondrite (L3)

History: Purchased by Ke Zuokai in Dec. 2016 from a Moroccan dealer.

Physical characteristics: The meteorite has a brown fusion crust and partially covered by rusty products. Chondrules and clasts ranging from white to dark gray are visible.

Petrography: The thin section shows abundant well-defined chondrules (up to 1.9 mm) of different kinds, such as PO, PP, POP, BO, BP and minor CC. The matrix is fine-grained silicates with minor metal and troilite. Mineral and chondrule clasts are also present. Metallic phase accounts for ~4 vol%.

Geochemistry: Silicates are unequilibrated. Olivine Fa1.0-52.0 (Fa23.2±15.1, PMD=52.1%, n=24); low-Ca pyroxene Fs1.2-24.0Wo0-1.3 (Fs14.2±8.5Wo0.6±0.5, Fs PMD=52.6%, n=32); minor Ca-rich pyroxene Fs8.4-7.8Wo44.4-44.9).
