Abstract
The sand cap on the enigmatically named Dutchman’s Cap (Olanda Kepuré) on the Lithunian Baltic Sea Coast has been labelled as ‘Holocene sand’, with no further details on its stratigraphy and depositional age. The Baltic Sea Coast is a paraglacial coastline, with many sand-rich reaches, influenced by changes in relative sea-level, sediment supply and windiness. Inland there are aeolian deposits of the European Sand Belt. This poster presents a high-resolution portable luminescence reader relative chronology, paired with three luminescence ages (quartz single-aliquot regeneration-protocol). The study confirms these deposits to be of very recent Holocene age, spanning the last ~1000 years. This is in line with groups of ages for coastal dune dynamics and beach ridge sediments in the Baltic Sea region. In particular, published records of dune migration on the nearby Curonian Spit dated by luminescence to 2.4 ± 0.2 to 2.2 ± 0.2 ka and 2.2 ± 0.2 to 1.1 ± 0.1 ka, and radiocarbon ages on palaeosols indicating soil formation include 2600-2400 cal yr BP and post 1900 cal yr B.P. (Bitinas et al., 2018).
