Northwest Africa 1879


Purchased 2003 June


Two very fresh, complete, crusted specimens (total weight 1624 g) were purchased from a dealer in Erfoud for A. and G. Hupé (xHupé) in 2003 June.  Classification and mineralogy (A. Irving and S. Kuehner, UWS): Mostly medium grained, relatively homogeneous assemblage of orthopyroxene (45%), plagioclase (15%), metal (20%), troilite (12%), chromite (8%) and accessory merrillite, with an unbrecciated, plutonic igneous texture.  The two-phase Fe-Ni metal grains consist of rounded regions of taenite (30 wt.% Ni) within kamacite (5 wt.% Ni).  Compositions of orthopyroxene (Fs29.8-31.0Wo3.1-3.5, FeO/MnO = 26.9-30.3) and plagioclase (An89.7-90.5Or0.3-0.6) are typical for mesosiderites, despite the lack of brecciation in this sample.  Both this sample and NWA 1827 appear to be part of a much larger, heterogeneous mesosiderite meteorite under study by A. Jambon (UPVI) and T. Bunch (NAU).  Specimens: type specimens, 22 g and one polished thin section, UWS; 7 g and one polished thin section, NAU*; main mass, xHupé.
