Writeup from MB 105:

Northwest Africa 10477 (NWA 10477)

(Northwest Africa)

Purchased: 2015

Classification: Enstatite chondrite (EL6)

History: The meteorite was purchased from the Moroccan meteorite dealer Hamza Lharbi.

Petrography: The meteorite dominantly consists of large, about 100 μm sized enstatite grains, less abundant albitic feldspar, troilite, alabandite and daubreelite. No relict chondrules were observed; metal is completely altered to iron oxides.

Classification: Although the metal is completely altered and the Si-content cannot be determined, the presence of alabandite strongly argues for EL (see e.g., Lin Y. and El Goresy A., 2002).
