Abstract
Bowman, Dan. Christiansen, Christian & Magaritz, Mordeckai: Late-holocene coastal evolution in the Hanstholm-Hjardemaal region, NW Denmark. Morphology, sediments and dating. Geo- grafisk Tidsskrift 89: 49–57. København 1989. Raised gravelly spits and beach ridges were studied as components of the late-holocene coastal evolution in NW Jutland. Two gravelly spits up to 8–9 m above the present sea level were dated 4000–4700 Y BP by oyster shells, i.e. of late Littorina/Tapes subboreal transgression. Dating of organic matter suggested general dune stabilization within the study area from 471 YBP. The data suggest that the study area operated as a semi- enclosed and sheltered embayment. The ridges indicate transgression of sediment masses arrested from the longshore drift, superimposed by moderate eolian accumulation.
