Resumen:
Dark Inclusions (DIs) are complex objects whose genesis is considered to be the result of two contrasting processes: a) those active in the CV3 chondrite parent body including metamorphism, frag-mentation, melting, aqueous alteration and subsequent dehydration [e.g. 1-7] and, b) those taking place in the solar nebula including aggregation and subsequent secondary alteration [e.g. 8-11]. Here, we combine a chemical and petrographic study of the Allende DI 4884-2B [12-13] and a ATEM study of Allende DI All-AF (NHM, Vienna) in order to get new insights onto the genesis of these objects.
