The northern Scandinavian Mountains had their main uplift in the Paleogene, while the southern Scandinavian Mountains and the South Swedish Dome were largely uplifted in the Neogene.[16][17] The uplift events were concurrent with the uplift of Eastern Greenland.[18] All of these uplifts are thought to be related to far-field stresses in Earth’s lithosphere. According to this view, the Scandinavian Mountains and the South Swedish Dome can be likened to a giant anticlinal lithospheric folds. Folding could have been caused by horizontal compression acting on a thin to thick crustal transition zone (as are all passive margins).[19][20] The uplift of the Scandinavian Mountains resulted in the progressive tilt of northern Sweden, contributing to create the parallel drainage pattern of that region.[21] As the South Swedish Dome uplifted, this resulted in the formation of a piedmonttreppen and the obstruction of the Eridanos River, diverting it to the south.[22]
