The Spanish Pyrenees are a linked system of regional thrust sheets and intermontane basins which formed during the Tertiary collision of the European and Iberian plates. The structural evolution of the Pyrenees was controlled by Mesozoic extensional structures and evaporite-bearing strata which served as the regional decollement and produced widespread pre- to postthrusting halotectonic folds. Palinspastic restoration of Cretaceous strata from the Pyrenean realm delineates a large normal-faulted embayment in the northern Iberian margin. Thicker sediments within the bay, coupled with the southward emplacement of the Cotiella-Montsec thrust sheet, caused underlying evaporites to flow toward the basin margins, producing folds such as the Mediano anticline.
