(Tables 1-2) Heavy mineral composition and median grain size of sediments obtained near 'Rote Kliff' west of Sylt, North Sea

The interpretation of 19 bore cores from the sea floor west of Rote Kliff (Isle of Sylt, North-Frisian Islands) gave information about the thickness of Holocene sand and the sediments below it; especially regarding their resistance to erosion in the area seaward of the beach-barrier. At the Same time, additional knowledge was obtained about the development of Sylt.对北弗里西亚群岛叙尔特岛红崖（Rote Kliff）西侧海底的19个钻孔岩芯（bore cores）开展解译工作，获取了全新世（Holocene）砂层及其下伏沉积物的厚度数据，重点明确了海滩障壁（beach-barrier）向海一侧区域内上述沉积物的抗侵蚀性能。与此同时，本研究还额外获得了关于叙尔特岛演化的相关认知。
