Writeup from MB 88:

Northwest Africa 1649

Morocco

Purchased 2002 October

Achondrite (eucrite, polymict)

A complete fusion-crusted stone of 70.8 g was purchased from a Moroccan dealer by A. and G. Hupé (xHupé).  Classification and mineralogy (A. Irving and S. Kuehner, UWS): Clasts of cumulate eucrite debris, composed of anorthite, exsolved pigeonite, silica, troilite, Ni-poor Fe metal and rare ilmenite.  Sparse (<5% by volume) clasts of diogenitic orthopyroxene (Fs20.1Wo1.2, FeO/MnO = 29.2) and rare, small basaltic eucrite clasts.  Unique components include a large (4 mm x 6 mm) quench-textured eucritic rock (composed of glass plus elongate, skeletal low-Ca pyroxene grains with more Fe-rich rims) and a fine grained ferroan intergrowth (breakdown of former pyroxferroite) consisting of fayalite+hedenbergite+silica in a polygonal texture.  Specimens: type specimen, 15 g, and one polished thin section, UWS; main mass, xHupé.
