Northwest Africa 13498 (NWA 13498)

(Northwest Africa)

Purchased: 2020 Feb

Classification: Ordinary chondrite (L3)

Petrography: (J. Gattacceca, CEREGE) Chondrite with large, packed, and imbricated chondrules (~700 µm). Opaque minerals are metal and troilite.

Geochemistry: Olivine Fa17.6±7.8, range Fa4.2-36.9, Fa PMD = 33%, Cr2O3 0.12±0.17 wt% (n=17). low-Ca pyroxene Fs11.2±7.1Wo0.9±0.8, range Fs2.1-25.8 (n=13).

Classification: Ordinary chondrite (L3). Texture reminiscent of "cluster chondrites". L group based on magnetic susceptibility and chondrule size. Estimated subtype 3.2-3.5 based on Fa PMD and Cr2O3 content of ferroan olivine.
