Writeup from MB 110:

Northwest Africa 14044 (NWA 14044)

(Northwest Africa)

Purchased: 2018 Sep

Classification: HED achondrite (Diogenite)

History: Purchased by Ziyao Wang in September 2018 from a Moroccan dealer at the Hubei Mineral and Gem Show in Huangshi City, China.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed predominantly of angular diogenitic orthopyroxene grains (exhibiting undulose extinction) plus some grains of olivine, calcic plagioclase and low-Ti chromite set in a sparse finer grained matrix containing accessory kamacite. Some olivine (as both individual grains and in a protogranular polycrystalline dunite clast in the studied thin section) is associated with symplectitic mesh aggregates of troilite.

Geochemistry: Orthopyroxene (Fs22.1-27.7Wo2.0-3.7, FeO/MnO = 28-32, N = 7), olivine (Fa26.4-27.1, FeO/MnO = 45-51, N = 6), plagioclase (An82.0-87.9Or1.4-0.3, N = 3).

Classification: Diogenite breccia (olivine-bearing).

Specimens: 13.7 g including one polished thin section at UWB; remainder with Mr. Z. Wang.
