Northwest Africa 10610 (NWA 10610)

(Northwest Africa)

Purchased: 2015

Classification: Carbonaceous chondrite (CK5)

History: Purchased by Gary in from Morocco, 2015.

Physical characteristics: Single stone with fusion crust. Saw cut surfaces reveal scattered, clearly defined, millimeter-sized, dark-colored chondrules, and a few faint CAIs, set in dark green-brown matrix.

Petrography: (C. Agee, UNM) This meteorite has distinct, equilibrated, olivine-rich chondrules. The recrystallized matrix consists mainly of olivine and lesser amounts of augite; trace low-Ca pyroxene. The mean diameter of plagioclase grains (~25 μm) indicates type 5. Olivine is nickel-rich and magnetite is present throughout.

Geochemistry: (C. Agee and M. Spilde, UNM) Olivine Fa33.2±0.3, Fe/Mn=127±11, NiO=0.53 wt%, n=11; augite Fs10.8±2.2Wo47.0±1.1, Fe/Mn=84±29, n=9; low-Ca pyroxene Fs27.2±0.0Wo2.3±2.0, Fe/Mn=73±1, n=2.

Classification: Carbonaceous chondrite (CK5)

Specimens: 7.03 g including a probe mount on deposit at UNM, Gary Fujihara holds the main mass.
