We have studied 2 dark inclusions in the Allende meteorite using transmission electron microscopy. One inclusions consists exclusively of subrounded aggregates of FeO-rich olivine and the second consists of chondrules which have been partially replaced by FeO-rich olivine set in a fine-grained matrix. The microstructures of olivine and diopside in both DIs are complex and both contain abundant pores and submicron inclusions of pentlandite, ilmenite and spinel. These phases are typically rimmed by a thin mantle of poorly graphitized carbon (PGC). The presence of PGC provides strong evidence that the olivine and diopside formed under similar conditions, after formation of the complex hydrocarbon precursors of the PGC at low temperatures. Many of the microstructures appear to be best reconciled with formation in a parent body environment as a result of aqueous alteration followed by metamorphism.
