dc.description.abstractHighly uplifted Middle Weichselian marine sediements at Høgjæren, SW Norway, have previously been explained by tectonic movements, glacial isostasy or a combination of these factors, whereas most recent studies seem to favour a model based on glacial isostasy. New evidence of uplifted Middle and Late Weichselian marine sediements in coastal areas of central and northern Norway, as well as from inland areas of central and southeastern Norway, strongly suggests a glacio-isostatic cause for the high-altitude location of most of these occurrences. The positions of these sediments also indicate a frequently fluctuationg ice sheet during the interval 18-50 ka BP. Repeated rapid ice retreat following heavy ice loading seems to be the most likely way to get marine sediments of both the same and different age intervals in such uplifted positions over such a wide geographical area. Significant deviations in the general glacial rebound trends of postglacial shoreline displacement in any of the areas discussed here have not been reported earlier. Hence, a tectonic cause for the land uplift of any of these locations is considered to be quite unlikely.
