Resumen:
Water- and (OH)-bearing phases in Ca-Al-rich inclusions(CAIs) are known from CM chondrites [e.g., 1] as well as frommicrometeorites and IDPs [e.g., 2-6]. They are widely believed tobe parent body alteration products of former non-hydrous phasesand comprise typically Fe, Mg phyllosilicates, which take theplace of, e.g., diopside, that commonly covers spinel + melilite +perovskite intergrowths [7]. Here we report on the first occurrenceof AlO(OH) as a major constituent in a CAI
