Basement rocks record Hercynian subduction and plutonism on the northern margin of Gondwana, which in the Permian and Triassic rifled into several microcontinents, thereby creating the eastern Mediterranean Neotethys ocean.
1988), which, together with the inferred crystallization age, were used to suggest that Permian-Carboniferous plutonism was a significant factor for economic mineralization in the Meguma Terrane (Cormier et al.
These data provide constraints on the timing of final movement on the orogen-parallel strike-slip Southern Uplands-Skerd Rocks Fault System, and have implications for correlations between Acadian plutonism in New England and in western Ireland.
Here we report new high precision U-Pb zircon ages for the late-Caledonian Galway Granite and use them (a) to elucidate more fully the duration and timing of granite magmatism in Connemara, (b) to place time constraints on the finality of motion on the Skerd Rocks Fault and the regional implications for the major orogen-parallel faults, and (c) to explore implications for cross-Atlantic correlations with Acadian granite plutonism in the New England Appalachians.
