Backscattered electron images of secondary mineral assemblages replacing åkermanitic melilite in Type B1, B2, FoB, and CTA CAIs: a grossular-monticellite-wollastonite, b−d grossular-monticellite, and e, f grossular-Al-diopside. All these mineral assemblages may contain minor clintonite, forsterite, spinel, Na-melilite, and wadalite. Na-melilite is commonly observed at the boundary between altered melilite and igneous anorthite (see a). Arrows in i indicate a boundary between grossulars with different MgO contents (dark, 3.7 and light, 2.3 wt%)
