South Swedish highlands

The South Swedish highlands (Swedish: Sydsvenska höglandet) is a hilly area covering large parts of Götaland in the southern parts of Sweden. Except for a lack of deep valleys the landscape is similar to the Norrland terrain found further north in Sweden.

Much of the highlands lies above 200 m.a.s.l. and there are large areas around the highlands that exceed 100 m.a.s.l. The highlands are centered on Småland but cover also large swathes of Scania, Halland, Västergötland, Östergötland and Blekinge. The highest point lies 377 m.a.s.l.

Within a geological context the highlands are the expression of the South Swedish Dome. The South Swedish Dome has been subsided and been uplifted multiple times by epeirogenic movements during the Phanerozoic. The dome has had periods of subsidence and burial in sediments have alternated with periods of exhumation and the formation of peneplains and hilly relief. The Sub-Cambrian peneplain of Late Neoproterozoic age is the oldest of the surfaces. It covers the eastern flank of the dome and its crest region where it is up-broken. The mesozoic-aged Sub-Mesozoic hilly relief covers the southern and western fringes of the dome, corresponding roughly with the counties of Halland, Blekinge and northeastern Scania. The youngest well-defined surface is the South Småland peneplain that formed in the Neogene. The Late Cenozoic uplift of the dome is tentatively related to far-field compressional stresses that has uplifted the region as a giant anticline-like lithosphere fold. As such it is similar to uplifted passive margins like the Scandinavian Mountains or the mountains of Western and Eastern Greenland.
