Integrated gravity and topography analysis in analog models:Intraplate deformation in Iberia

Trends in the topography of the Iberian Peninsula show a pronounced contrast.In the western part of the Iberian microplate the main topographic highs trend E-W toNE-SW and are periodically spaced with wavelengths of 250 km. Conversely, in thenortheastern part, the region of the Iberian Chain, topogr...
