Lithospheric-scale folding in Iberia from the perspective of analogue modelling .

[EN] The Iberian Peninsula is characterized by the presence of regularly spaced and generally E-W to NE-SW trending mountain ranges with mainly E-W crustal-scale thrusts across the wholePeninsula. Intraplate deformation resulting from the convergence between the African and Europeanplates during the...
