(Northwest Africa)

Purchased: 2006

Classification: Ordinary chondrite (L3-6)

History: The meteorite was found by an anonymous finder in northwest Africa and bought by the main mass holder in Morocco.

Physical characteristics: One fragment of 50 g partly covered with fusion crust was found.

Petrography: The meteorite is a chondritic breccia composed of L3 to L6 clasts set into a fine-grained clastic matrix. Plagioclase grain size in L5 clasts is about 30 μm and in L6 clasts about 70 μm. Olivine and pyroxene in L3 clasts are highly unequilibrated with Fa22.9±8.8 (7.8-44.2, n=53) and Fs15.2±6.3Wo1.0±1.0 (Fs 1.6-24.4Wo0.2-4.5, n=34). In L5 and L6 clasts olivine and pyroxene are equilibrated at Fa23.5±0.2, n=15 and Fs19.8±0.5Wo1.0±0.7, n=11.
