Geology of Sylt

MarMic

October 2004


Relevant Gelogical Ages at Sylt Holocene - Miocene

  • Holocene 10.000- present

  • Pleistocene1.8 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

  • Pliocene1.8 Mio-5 Mio

  • Miocene5 Mio-24 Mio

Miocene


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

  • Recent Dune formation

  • Solifluction of Boulder Clay (Weichsel)

  • Boulder Clay (Saale)

  • Kaolin Sand (Pliocene)

  • Limonite Sandstone (Pliocene)

  • Clay (upper Miocene/lower Pliocene)
