BSE images (a, c) and combined x-ray map (b) in Mg Kα in red, Ca Kα in green, and Al Kα in blue of hibonite-rich CAI 2–119 from ALHA77307. The regions outlined in (a) are shown in detail in (c). In this CAI, individual nodules consist of hibonite grains partially to completely surrounded by spinel with minor perovskite.
