OFFICIAL CLASSIFICATION DATA SOURCE: Physical characteristics: All specimens (many of which have a flattened slab-like form) lack fusion crust and exhibit medium-brown, "knobby" exterior surfaces. Interiors of stones have an overall tan to pinkish hue with obvious light gray, dark gray and whitish clasts plus some visible small grains of metal. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Two separate endcut specimens were studied. Both are samples of the same breccia material, composed of mineral clasts of anorthite, olivine, pigeonite, subcalcic augite, augite and orthopyroxene, plus sparse lithic clasts of spinel troctolite, set in a fine grained microvesicular matrix containing accessory altered kamacite, troilite, taenite and pentlandite. Secondary calcite is present pervasively in one of the two specimens studied and in places may be replacing original glass. Olivine grains in both studied specimens have been partially replaced by inhomogeneous phyllosilicate-rich assemblages, which apparently are hydroxylated (as evidenced by systematically low oxide analytical sums of 88-90 wt.% and absence of measurable F and Cl), and which are very Mn-deficient (yielding very elevated FeO/MnO ratios in the range 150-250). Troctolitic clasts are composed predominantly of anorthite and olivine with accessory Cr-pleonaste, low-Ca pyroxene and/or higher-Ca pyroxene. Geochemistry: Olivine (Fa17.3-32.1, FeO/MnO = 76-100, N = 15), anorthite (An95.4-99.0Or0.2-0.0, N = 7), pigeonite (Fs18.2-26.8Wo12.4-4.7, FeO/MnO = 47-54, N = 6), orthopyroxene (Fs16.0-21.6Wo2.2-3.7, FeO/MnO = 51-66, N = 4), subcalcic augite (Fs15.9Wo31.0, FeO/MnO = 41), augite (Fs7.6-7.9Wo42.9-45.6; Fs13.8Wo38.9; FeO/MnO = 36-48, N = 3). Troctolite clast: olivine (Fa18.2-21.2, FeO/MnO = 84-92, N = 4), anorthite (An97.7Or0.0), pleonaste (mg = 0.721, cr = 0.093). Classification: Lunar (feldspathic regolithic breccia, partially hydrothermally-altered).
