1 Geology of Sylt MarMic October 2004

2 Relevant Gelogical Ages at Sylt Holocene - Miocene Holocene present Pleistocene1.8 Mio B.P. – Weichsel (glacial) B.P. – Eem (interglacial) – Saale (glacial) – Holstein (interglacial) – Elster (Glacial) Pliocene1.8 Mio-5 Mio Miocene5 Mio-24 Mio

3 Geological Map of Sylt Miocene Pliocene

4 Reconstruction of the geological history Deposition of Miocene Clays (warm conditions Slow uplift (Salt domes?), shallower conditions with deposition of coastal (sandy) facies: Pliocene Limonite Deposition of riverine sediments from a large river system in the baltic region (Pliocene Kaolin sand) Ice ages – Some Elster Deposits – Large Saale Deposits – Erosion during the Eem Interglacial leaving some outcrops – No deposits during the Weichsel Ice Age – Recent sea level rice, formation of the Wadden Sea and barrier Islands
