%X The allochthonous terranes of northwest Iberia can be correlated with specific paleogeographicrealms of the continental masses and intervening oceans involved in the Variscan collision.Assuming that the existing ophiolites represent the suture formed by the closure of theRheic ocean, the units in the footwall to the suture correspond to the outer edge of the Gondwanacontinental margin, and the units in the hanging wall are interpreted as fragments of theconjugate margin, represented by the Meguma terrane. This correlation establishes a preciselink between circum-Atlantic terranes, and makes it possible to draw a relatively simple scenarioof the successive tectonothermal events recorded. Following the amalgamation of Avalonto Laurentia, the remaining outboard terranes underwent a progressive accretion to this continentthat ended with the collision between Laurentia and Gondwana.
