South Småland peneplain

The South Småland peneplain (Swedish: Sydsmåländska peneplanet) is a large flattish erosion surface, a peneplain, formed during the Tertiary, covering large swathes of southern Småland and nearby areas in Southern Sweden.

[3][2] To the south and west (chiefly Halland and Blekinge) the peneplain transitions into Mesozoic-aged hilly surfaces.

[2] In a 2013 study the surface is described as extending over an altitude range of 100 to 150 meters above sea level,[2] while in a subsequent 2017 study the main surface is said to range from 175 to 125 m a.s.l.

[3] It is possible that the Kvärkabäcken and Skäralid streams that traverse the Söderåsen horst in Scania are old antecedent rivers that once flowed through the South Småland peneplain.

[5] The existence of this plain was first noted by Sten De Geer in 1913 who termed it Smålands urbergslätt.
