Northwest Africa 11070 (NWA 11070)

(Northwest Africa)

Purchased: 2016 Apr

Classification: Carbonaceous chondrite (CV3)

History: Purchased by Darryl Pitt in April 2016 from a dealer in Mauritania.

Petrography: (A. Irving and S. Kuehner, UWS) Granular chondrules (apparent diameter 900 ± 700 µm) and relatively abundant irregularly-shaped, fine grained CAI (some containing grossmanite) are set in a red-brown matrix (~25 vol.%).

Geochemistry: Olivine (Fa1.2-66.7, N = 3), orthopyroxene (Fs0.7-1.1Wo1.3-0.8, N = 3), Al-Ti-diopside in CAI (Fs0.3Wo53.3, Al2O3 = 6.7 wt.%, TiO2 = 0.47 wt.%), grossmanite in CAI (Fs0.0Wo67.2, Al2O3 = 20.5 wt.%, TiO2 = 8.6 wt.%).

Classification: Carbonaceous chondrite (CV3).

Specimens: 20.4 g including one polished thin section at UWB; remainder with DPitt.
