AB Rhenium-depletion model ages (TRD) of sulfi des in peridotite xenoliths from the subcontinentalmantle beneath central Spain (the Calatrava volcanic fi eld) reveal that episodes ofmantle magmatism and/or metasomatism in the Iberia microplate were linked to crustalgrowth events, mainly during supercontinent assembly and/or breakup at ca. 1.8, 1.1, 0.9,0.6, and 0.3 Ga. A synthesis of available in situ and whole-rock Os-isotope data on mantlederivedperidotites shows that this type of mantle (maximum TRD of ca. 1.8 Ga) is widespreadin the subcontinental mantle of Europe and Africa outboard from the Betics-Maghrebides-Appenines front. In contrast, the mantle enclosed within the Alpine domain records TRD as oldas 2.6 Ga, revealing a previously unrecognized Archean domain or domains in the central andwestern Mediterranean. Our observations indicate that ancient fragments of subcontinentallithospheric mantle have played an important role in the development of the present architectureof the Mediterranean lithosphere.
