Carpenter, WUSL ) Well-formed granular, BO and PO chondrules (apparent diameter 710 ± 450 µm, N = 25) plus irregularly-shaped, very fine grained CAI are set in a fine grained matrix (~20 vol.%, sepia brown in thin section). Accessory phases include kamacite, taenite, Cr- magnetite and pentlandite. One unusual chondrule contains barred olivine plus interstitial melilite accompanied by minor gypsum . Geochemistry: Olivine (Fa 20.4±21.3 , range Fa 1.7-59.2 , N = 8), low-Ca pyroxene (Fs 0.8±0.1 Wo 1.0±0.5 , range Fs 0.8-0.9 Wo 0.7-1.6 , N =3), diopside (Fs 0.8±0.4 Wo 43.8±0.6 , range Fs 0.0.5-1.1 Wo 44.2-43.3 , N =23), magnetite (Cr 2 O 3 = 1.2-1.5 wt.%, N = 2).
