The deglaciation sea level and the marine limit in the Laholm—Halmstad area, Sweden

Abstract

Abstract Differences in sea level determinations for the Laholm-Halmstad area are up to 20 metres. This is mainly due to the existence of two different sea levels, a lower, older deglaciation level and a higher, younger transgressive ML level. The topset/foreset contact in ice-marginal glaciofluvial deposit is used as a reference plane, RP, from which sea level at the time of their deposition is deduced. This is based upon the assumption that the RP is situated between 0.5 and 4 m below the mean sea level. The results of this study seem to support this assumption, however, a systematic study of variations in the RP levels within individual deposits is necessary to test this assumption. The deglaciation sea level is deduced to be +51 to +52 m in the southern part of the area and +55 to +56 m in the northern part. The ML values, based upon the limit of wave washing, are compiled from the literature and indicate a ML of +60 to +61 m in the south and +66 to +69 m in the north. A hiatus, representing a subaeri...
