Crustal thickening and deformation sequence in the footwall to the suture of the Variscan belt of northwest Spain

The sequence of formation and propagation of structures, as well as the evolution of crustal thickening, in the Variscan belt of northwest Spain are proposed in this paper. The foreland of this mountain belt shows thin-skinned tectonics. A polyphase deformation with associated regional metamorphism is recognized in the hinterland zones. Two important culminations, the Narcea and Lugo antiforms, are present in an E-W cross-section through the...
