The marine holocene of sylt - discussion of the age and facies

Abstract

Investigation of the marsh area of Sylt during 1965-66-67 yielded new data regarding the development of Sylt during the Holocene. Three transgressions of the sea were established. The deposits of the first belong to the Calais (according to Brand et al. 1966) and the others to the Dunkirk. The ages of the transgressions were determined by means of 14C-analysis and cultural layers. South of Westerland, the finegrained facies of the second transgression indicates that the area was well protected by the “Geestkerne" and the southern beach-barrier of the island.
