Writeup from MB 107:

Northwest Africa 4669 (NWA 4669)

(Northwest Africa)

Purchased: 2006

Classification: Carbonaceous chondrite (CV3)

History: In 2006, A. Pani purchased a single stone of 369 g in Erfoud, Morocco.

Physical characteristics: The stone is a compact rock with a wind-polished surface of grayish-black color. Fusion crust is not present.

Petrography: (F. Brandstätter, NHMV) The meteorite consists mainly of abundant chondrules (mean diameter 1.05 mm), minor AOAs and CAIs set in a fine-grained matrix. CAIs (fine-grained) are sparse and on average small (<2-3 mm). The matrix is dominated by Fe-rich olivine, magnetite, minor pentlandite, and very rare metal grains.

Geochemistry: Chondrule olivine (Fa0.2-31.3, mean Fa6.7, N=68), matrix olivine (Fa8.9-63.8, mean Fa47.3, mean NiO = 0.09 wt%, N = 26), magnetite (Al2O3 = 1.18 wt%, Cr2O3 = 0.31 wt%, TiO2 = 0.15 wt%, NiO = 0.05 wt%, N = 10)

Classification: Carbonaceous chondrite (CV3)

Specimens: 21.7 g is on deposit at NHMV. Pani holds the main mass.
