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. The uplift events were concurrent with the uplift of Eastern Greenland. 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). The uplift of the Scandinavian Mountains resulted in the progressive tilt of northern Sweden, contributing to create the parallel drainage pattern of that region. 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.
