Northwest Africa 15972 (NWA 15972)

Morocco

Purchased: 2022

Classification: Ordinary chondrite (LL3)

History: Found in Morocco, and bought by Jean Redelsperger in Guelmim in 2022

Physical characteristics: Some fragments are partially crusted.

Petrography: (J. Gattacceca, CEREGE) Chondrite with packed chondrules ~800 µm set in a fine-grained matrix. Opaque minerals are metal and troilite.

Geochemistry: Olivine Fa14.2±8.1, range Fa0.4-29.9, Fa PMD 46% (n=18). Cr2O3 in ferroan olivine 0.157±0.089 wt% (n=17). Low-Ca pyroxene Fs8.4±3.5Wo1.8±1.4 (n=5).

Classification: Ordinary chondrite (LL3). LL group based on chodrule size and magnetic susceptibility. Subtype >=3.2 based on the Cr2O3 content of ferroan olivine. Estimated subtype 3.2 based on the olivine Fa PMD.

Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.
