Northwest Africa 5889 (NWA 5889)

(Northwest Africa)

Purchased: 2008

Classification: Primitive achondrite (Winonaite)

History: The meteorite was purchased from a meteorite dealer in Besancon, France.

Physical characteristics: Three small brownish fragments without fusion crust.

Petrography: The meteorite displays an equilibrated texture with abundant 120° triple junctions. Low-Ca pyroxene is the most abundant phase with forsteritic olivine, augite, and feldspar grains being subordinate. Grain sizes are typically 100 to 200 μm. Minor phases include kamacite, schreibersite, and troilite. Contains veinlets of metal or Fe-oxide throughout. No chondrules were observed.

Geochemistry: olivine: Fa4.6±0.1 (Fa4.4-4.8, FeO/MnO=27±3, n=12); low-Ca pyroxene: Fs6.8±0.2Wo1.8±0.1 (Fs6.3-7.1Wo1.6-2.0, FeO/MnO=29±6, n=12); Ca-pyroxene: Fs2.6±0.2Wo45.6±0.3 (Fs2.4-2.9Wo45.2-46.2, n=7); feldspar: An12.4±1.2Ab84.9±1.0Or2.7±0.3, n=9
