(Northwest Africa)

Purchased: 2010 June 17

Classification: HED achondrite (Diogenite)

Petrography: (A. Irving and S. Kuehner, UWS): Complex polymict breccia composed mostly of diogenitic clasts and debris (yellow-brown in thin section), with sparse material derived from cumulate eucrites.

Geochemistry: Orthopyroxene (Fs32.2-34.2Wo3.5-2.7; Fs60.9Wo3.5; FeO/MnO = 30.9-31.6), magnesian clinopyroxene (Fs12.8-12.9Wo44.3-44.6; FeO/MnO = 25.4-25.9), more ferroan clinopyroxene (Fs30.0Wo41.8; FeO/MnO = 33.6), sparse shocked calcic plagioclase, chromite and troilite.
