Northwest Africa 11066 (NWA 11066)

(Northwest Africa)

Purchased: 2016 Nov

Classification: Ureilite

History: Purchased by Darryl Pitt in November 2016 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Relatively coarse grained aggregate of ~85 vol.% olivine and ~12 vol.% low-Ca pyroxene (both orthopyroxene and pigeonite) with accessory graphite and minor calcite. Olivine has reduced magnesian rims containing fine grained, blebby Fe metal. Both olivine and pyroxene have been completely recrystallized to myriad subgrains.

Geochemistry: Olivine (cores Fa22.9-23.9; rim Fa6.5), orthopyroxene (Fs15.0Wo3.6), pigeonite (Fs19.7Wo6.6).

Classification: Ureilite (olivine-rich, recrystallized).

Specimens: 23.5 g including one polished thin section at UWB; remainder with DPitt.
