Depositional history of the Neoproterozoic Visingsö Group, south-central Sweden

Author

  • Viktor Ahrenstedt

Summary, in English

The Neoproterozoic sedimentary rocks of the Visingsö Group are one of few remaining rocks from this time. They provide a vital clue to understanding how the landscape looked at this time. The various environmental factors that prevailed and affected deposition are key to paint a bigger picture. The Visingsö Group shows how a local, fairly shallow, environment is subject to a long-term transgression. The three different formations in the Visingsö-Group represent three different depositional settings: The sandstones of the lower formation represent a fluviatile deltaic setting, the alternating beds of the middle formation represent a pro-delta environment and the shales of the upper formation represent a depositional setting alternating between marine and tidal-influenced.
