Structure of the South-Western Part of the Curonian Spit

Contrary to prevailing assumptions, the south-western part of the Curonian Spit—a prominent coastal barrier in the Baltic Sea—is not primarily a product of Holocene sedimentary processes but rather an ancient fluvioglacial plain. This finding challenges the long-held view that such features form through wave action and aeolian deposition. Through detailed geological and geomorphological analysis, including fieldwork comparing deposits from the Curonian and Vistula Spits, researchers identified remnants of a pre-Holocene alluvial or fluvioglacial landscape within the lagoon shore of the Vistula Spit. This discovery reshapes understanding of the region's geological history.
