Northwest Africa 10508 (NWA 10508)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (L3)

History: Purchased by an anonymous collector from a dealer at the Munich Show in 2005 and subsequently donated to the PSF.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed spherical chondrules (apparent diameter 1.0±0.7 mm; one 2.7 mm) are set in a finer matrix. Olivine is mostly equilibrated but magnesian cores are present in some grains.

Geochemistry: Olivine (cores Fa8.8; predominantly Fa25.3-25.8, N = 4; Cr2O3 in ferroan olivine 0.02-0.07 wt.%), orthopyroxene (Fs3.1-10.2Wo0.5-1.0, N = 3), clinopyroxene (Fs12.7Wo35.5; Fs15.7Wo28.0, N = 2).

Classification: Ordinary chondrite (L3).

Specimens: The entire specimen including one polished thin section is at PSF.
