Achondrite (eucrite, cumulate)

A complete fusion-crusted stone (259 g) was purchased from a Moroccan dealer by A. and G. Hupé (xHupé). Classification and mineralogy (A. Irving and S. Kuehner, UWS): Fine-grained with clasts of anorthite, exsolved pigeonite, chromite, ilmenite, metal, troilite and silica in a complex matrix which has the texture of a eutectoid melt of plagioclase + pyroxene. FeO/MnO is 32.8 for orthopyroxene and 34.8 for clinopyroxene. Veinlets of glass probably are quenched impact melt. Specimens: type specimen, 20 g, and one polished thin section, UWS; main mass, xHupé.
