Diopside in the chondrules in Y-691 (EH3), most of which include enstatite as phenocrysts, occurs in three different modes; (1) diopside rimming some of the enstatite crystals, (2) single crystals as phenocrysts of the chondrules, and (3) single crystals of diopside enriched in aluminum in one chond...
