Typ (englisch):

Lunar meteorite (feldspathic breccia)

Mineralzusammensetzungen und Geochemie (englisch):

Abundant partly devitrified, glassy matrix (with swirly texture) containing embedded small mineral and lithic clasts. Minerals are olivine, orthopyroxene, pigeonite, augite, anorthite, ilmenite, troilite and minor kamacite. Olivine (Fa33.4-34.5, FeO/MnO = 83-96), orthopyroxene (Fs34.7Wo2.3, FeO/MnO = 53), pigeonite (Fs25.8Wo6.3, FeO/MnO = 53), augite (Fs14.5Wo41.7; Fs33.5Wo39.5, FeO/MnO = 38-68), anorthite (An96.2-98.5Or0.1). Bulk composition: INAA of subsamples gave mean abundances of FeO 5.6 wt.%, and (in ppm) Sc 31, La 13.2, Sm 6.2, Eu 1.39, Yb 4.0, Th 1.9.
