Exhumation of high-pressure (P) rocks may require a long path and multiple deformation phases. During this journey, late faults and folds can introduce changes to the primary tectonic stacking and lead to misleading conclusions regarding subduction p

Aspects of the evolution of the Pan-African-Cadomian arc have been recognized in several European massifs. The Ossa-Morena Complex (SW Iberian Massif) is one of the best-preserved sections of this paleo-Gondwana margin. In this domain, recent studies

[EN] The Porvenir serpentinites are an ~600-m-thick body of meta-peridotites exposed in SW Iberia (Variscan Orogen). The serpentinites occur as a horse within a Carboniferous, out-of-sequence thrust system (Espiel thrust). This thrust juxt

The Badajoz-Córdoba Unit (BCU, SW Iberian Massif) is a Variscan high-P unit mainly constituted by metapelites, metagreywackes, orthogneisses, Grt-amphibolites, and retrogressed eclogites (high-P metamorphism at c. 377 Ma). Discovery of rare metapeli

The Cubito-Moura Unit is a high-P metamorphic succession that occurs in the southern part of the Ossa-Morena Complex (SW Iberian Massif). It includes a series of metasedimentary, metafelsic and metamafic rocks affected by a high-P, low to intermediat
