Northwest Africa 10559 (NWA 10559)

(Northwest Africa)

Purchased: 2015 Dec

Classification: Carbonaceous chondrite (CK3)

History: Purchased by in Temara, Morocco, by Adam Aaronson in December 2015.

Petrography: (A. Irving and S. Kuehner, UWS) Separated, well-formed granular chondrules (apparent diameter 1.2±0.6 mm; one 3.8 mm) containing Cr-magnetite plus sparse irregularly shaped, very fine grained, whitish mineral aggregates (up to 4.5 mm in longest dimension) are set in a finer matrix containing Cr-magnetite, intermediate plagioclase and Ni-bearing pyrrhotite. Relict forsterite cores are present in olivine. The fine grained aggregates consist of intermediate plagioclase, orthopyroxene, diopside, olivine, pleonaste spinel and minor ilmenite.

Geochemistry: Olivine (relict cores Fa0.3-0.6; predominantly Fa33.9-34.4, FeO/MnO = 108-109, N = 4), clinopyroxene (Fs0.8Wo38.6; Fs9.2Wo49.3, N = 2).

Classification: Carbonaceous chondrite (CK3).

Specimens: 20.1 g including one polished thin section at UWB; main mass with Aaronson.
