Sparse CAI consisting mainly of Mg-Al spinel, gehlenite and perovskite, with rims of Al-Ti-rich clinopyroxene. Veins of anorthite present.

Geochemistry: Mafic silicates are very Mg-rich (mg > 97), metal (5 wt% Ni).Oxygen Isotopes: (D. Rumble, CIW) Analyses of two whole rock fragments by laser fluorination gave δ18O = -1.12, -2.71; δ17O = -4.45, -6.36; Δ17O = -3.860, -4.934 (all ‰).
