Northwest Africa 8387 (NWA 8387)

(Northwest Africa)

Purchased: 2014

Classification: Ordinary chondrite (LL3)

History: Purchased by Blaine Reed in Tucson, February 2014.

Physical characteristics: Single stone with oxidized weathered exterior. Saw cut reveals chondrules and metal/sulfide set in a light gray matrix.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount reveals numerous chondrules, some poryphyritic with igneous zoning and mesostasis. Kamacite, troilite, and iron oxide present.

Geochemistry: (C. Agee, N. Muttik, UNM) Olivine Fa27.1±2.1, Fe/Mn=55±2.1, n=36; low-Ca pyroxene Fs17.1±8.0Wo0.8±0.7, Fe/Mn=38±18, n=20.

Classification: Ordinary chondrite (LL3, W2). Based on σ-Fa, this is likely near petrologic type 3.9.
