We conducted a detailed study of a unique metapelite from the ultrahigh-pressure (UHP) Brossasco-Isasca unit (Dora-Maira Massif). It consists of pre-Alpine porphyro-blastic garnet (Grt1), Alpine-age idioblastic garnet (Grt2), phengite, and kyanite. The pre-Alpine garnet contains inclusions of staurolite, kyanite, paragonite, chloritoid, chlorite, quartz, ilmenite, and rutile. The metapelite also includes quartz aggregates after former coesite and fine-grained paragonite aggregates after jadeite. Late chlori-toid and staurolite idioblasts, first reported from a Brossasco-Isasca unit metapelite, are also present in the rock matrix: they grew randomly across the main Alpine UHP foliation defined by phengite. The decompression pressure-temperature (P-T)...
