  1. Geology of Sylt MarMic October 2004

  2. Relevant Gelogical Ages at Sylt Holocene - Miocene • Holocene 10.000 - present • Pleistocene 1.8 Mio - 10.000 B.P. • Weichsel (glacial) 115.000 - 10.000 B.P. • Eem (interglacial) 128.000 - 115.000 • Saale (glacial) 128.000 - 347.000 • Holstein (interglacial) 347.000 - 370.000 • Elster (Glacial) 370.000 - 475.00 • Pliocene 1.8 Mio - 5 Mio • Miocene 5 Mio - 24 Mio

  3. Geological Map of Sylt Pliocene Miocene

  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
