| Abstract: | A presença de rochas migmatíticas (metatexitos e diatexitos) na região de Mundão (Zona
Centro-Ibérica) mostra que as condições de fusão parcial foram atingidas durante o metamorfismo
regional varisco neste sector. Com base nas relações com a deformação, foi possível identificar várias
gerações de leucossomas e demonstrar que o processo de anatexia começou relativamente cedo, durante
os estádios finais do engrossamento crustal (D1) e continuou durante a tectónica extensional (D2) e
transcorrente (D3) subsequentes. The occurrence of migmatites (metatexites and diatexites) in the Mundão region (Central Iberian Zone) shows that the Variscan regional metamorphism reached the partial melting conditions in this sector. According to the relationships with the deformation, it was possible to identify several generations of leucosomes and demonstrate that crustal anatexis started relatively early, during the last stages of crustal thickening (D1) and continued during subsequent extensional (D2) and transcurrent (D3) tectonics. |
