Writeup from MB 106:

Northwest Africa 11041 (NWA 11041)

(Northwest Africa)

Purchased: 2015

Classification: Rumuruti chondrite (R3-6)

History: The meteorite was bought in 2015 from a Moroccan meteorite dealer at the mineral fair in Munich, Germany.

Petrography: The meteorite is a breccia with light and dark colored lithic fragments of all petrological types (3 to 6) and impact-melt clasts set into a fine-grained, clastic groundmass. Olivine is the dominant mineral phase in all lithologies and particular Fe-rich in type 6 clasts. Orthopyroxene displaying typical patchy zoning is only found in unequilibrated lithologies. Minor phases include albitic feldspar, augite, chromite, pentlandite and pyrrhotite. FeNi metal is virtually absent.

Geochemistry: Olivine in type 6 lithology: Fa38.1±0.2, n=14; olivine in type 3 lithology: Fa25.3±8.5 (1Fa1.6-44.6, n=75); low-Ca pyroxene in type 3 lithology, Fs16.0±7.8Wo1.1±0.9 (Fs1.1-26.9Wo0.1-5.0, n=51)
