Phases of aeolian accumulation on the Vistula Spit (Southern Baltic Sea) in the light of TL dating and analysis of a digital elevation model

The genesis of the Vistula Spit (Southern Baltic Sea) in the Postlitorina period is regarded as occurring by gradual addition of successive dune ridges along the entire length of the form. Based on the degree of soil profile development and radiocarbon dating of organic sediments three main stages of aeolian processes are usually recognized. GIS analysis of a digital elevation model (DEM) and thermoluminescence dating of dune sand supports the model of progressive development of dune ridges, and has identified four periods of intense aeolian activity. These were established 5860–5400, 1930–1610, 1200–900 years ago from the present, and from 500 years ago.
