Northwest Africa 11079 (NWA 11079)

(Northwest Africa)

Purchased: 2016 Sep

Classification: Carbonaceous chondrite (CV3)

History: Purchased by Bob Falls in September 2016 from a Moroccan dealer at the Denver Show.

Petrography: (A. Irving and S. Kuehner, UWS) Granular chondrules (apparent diameter 700±500 μm; some spherical, some with concentric rims, some more irregular in shape) plus abundant irregularly-shaped, fine grained CAI and sparse aggregates of fine grained olivine+pentlandite are set in a deep brown matrix (~35 vol.%). Minerals identified in CAI include hedenbergite, pleonaste, perovskite, sodalite, Ca-K-bearing nepheline, awaruite, troilite and rare ilmenite.

Geochemistry: Olivine (Fa0.4-46.7, N = 3), orthopyroxene (Fs0.8-1.1Wo1.2-4.0, N = 3), clinopyroxene (Fs0.9-1.6Wo32.2-37.8, N = 2), ferroan augite (Fs48.1Wo50.5).

Classification: Carbonaceous chondrite (CV3).

Specimens: 29.6 g including one polished thin section at UWB; remainder with Mr. R. Falls.
