Northwest Africa 11243
History: Purchased by Ken
Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral fragments and sparse olivine noritic lithic clasts in a finer grained matrix. Minerals are anorthite, olivine, orthopyroxene, pigeonite, ferropigeonite, fayalite, silica polymorph, Al-Ti-chromite, kamacite, ilmenite, troilite and calcite.
Geochemistry: Olivine (Fa23.3, FeO/MnO = 101), orthopyroxene (Fs12.9-26.3Wo4.2-2.4, FeO/MnO = 60-74, N = 2), pigeonite (Fs30.1Wo8.7, FeO/MnO = 66), ferropigeonite (Fs61.1Wo24.4, FeO/MnO = 64), fayalite (Fa87.4, FeO/MnO = 80), anorthite (An97.7-98.3Or0.3-0.1, N = 2).
Classification: Lunar (feldspathic breccia).
Specimens: 16.24 g including one polished slice at UWB; remainder with Mr. K. <Regelman.
These two stones may not be paired, but they are very similar in composition.
