Fig. 8From: Infiltration metasomatism of the Allende coarse-grained calcium-aluminum-rich inclusionsa, c Combined x-ray elemental maps in Mg (red), Ca (green), and Al (blue), and (b, d−f) backscattered electron images of the interior regions of Type C CAIs (a, b) 160 and (c−f) 100. Regions outlined in c and e are shown in detail in d–f, respectively. Lacy melilite composed of åkermanitic melilite with numerous rounded inclusions of anorthite is pseudomorphically replaced to various degrees by grossular-forsterite-monticellite and grossular-Al-diopside. Anorthite groundmass around melilite pseudomorphs shows little evidence for alteration: small amount of Na-melilite occurs along edges of melilite pseudormorphsBack to article page
