Early carboniferous wrenching, exhumation of high-grade metamorphic rocks and b...
Pereira, M. Francisco; Chichorro, M.; Silva, J. Brandão; Ordonez-Casado, B.; Lee, James K.W.; Williams, Ian S.New U–Pb and 40Ar–39Ar geochronology and structural data from high- tomedium grade metamorphic shear zones of the Ossa-Morena Zone, and structural data from Early Carboniferous basins (Ossa-Morena Zone and South-Portuguese Zone), place additional constraints on the Variscan tectonics in SW Iberia. A zircon U–Pb age of 465±14Ma (Middle Ordovician) measured on migmatite from the Coimbra–Cordoba shear zone is inte...
