Fig. 5From: Infiltration metasomatism of the Allende coarse-grained calcium-aluminum-rich inclusionsa−d Backscattered electron images, e combined x-ray elemental map in Mg (red), Ca (green), and Al (blue), and f elemental map in Mg of a vein crosscutting gehlenitic melilite mantle around Type B1 CAI TS-23. Regions outlined in a are shown in detail in b, c, and d−f, respectively. Towards the CAI interior, the melilite becomes more åkermanitic. The mineralogy of the vein changes towards the CAI interior from anorthite-rich to grossular-rich; minor phases include Al-diopside, forstetrite, and spinel. Åkermanitic melilite in the core is replaced by coarse-grained grossular, monticellite, wollastonite, and minor wadaliteBack to article page
