Northwest Africa 10827 (NWA 10827)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CM2)

History: Purchased by Gary Fujihara from Morocco, 2016.

Physical characteristics: Single stone, fusion-crusted. A saw cut shows a few scattered chondrules, crystal fragments, and small CAIs set in a dark-colored matrix.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows a low density of porphyritic chondrules (most, irregular in shape), chondrule fragments, and olivine grains. Phyllosilicate-bearing matrix makes up approximately 75% of this meteorite.

Geochemistry: (C. Agee and M. Spilde, UNM) All olivine Fa15.4±19.0, n=27; ferroan olivine Fa31.0±16.5, Fe/Mn=93±36, Cr2O3=0.36±0.10 (wt%), n=13; forsterite Fa0.8±0.3, n=14; enstatite Fs1.1±0.4Wo1.0±0.2, n=10.

Classification: Carbonaceous chondrite (CM2)
