Writeup from MB 109:

Northwest Africa 13504 (NWA 13504)

(Northwest Africa)

Purchased: 2019 Oct

Classification: Ordinary chondrite (L3.10)

History: Bought from a dealer from northwest Africa.

Physical characteristics: Single oriented stone.

Petrography: (J. Gattacceca, CEREGE) Chondrite with packed large and well-delineated chondrules (average apparent diameter 730±340 μm, n=43). Opaque minerals are metal and troilite.

Geochemistry: Olivine Fa20.2±14.3, Fa PMD = 61% (n=15), Cr2O3 in ferroan olivine 0.28±0.21 wt% (n=14). Low-Ca pyroxene Fs14.3±9.9Wo2.0±2.1 (n=16).

Classification: Ordinary chondrite L3.10. Likely L group based on magnetic susceptibility interpreted in the light of weathering grade and chondrule size. Subtype based on Cr2O3 content of ferroan olivine.

Specimens: Type specimen at CEREGE. Main mass with Kuntz.
