1. The Neoproterozoic Visingsö Group of southern Sweden : lithology, sequence stratigraphy and provenance of the Middle Formation
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The depositional setting of the Neoproterozoic Visingsö Group has long been a subject of discussion. This study aims to provide additional insights into the lithological composition and provenance of the sediments and to provide a sequence stratigraphic framework in order to define the depositional setting.

2. Depositional history of the Neoproterozoic Visingsö Group, south-central Sweden
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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. LÄS MER
3. Biodiversity of Organic-Walled Eukaryotic Microfossils from the Tonian Visingsö Group, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The diversification of unicellular, auto- and heterotrophic protists and the appearance of multicellular microorganisms is recorded in numerous Tonian age successions worldwide, including the Visingsö Group in southern Sweden. The Tonian Period (1000-720 Ma) was a time of changes in the marine environments with increasing oxygenation and a high input of mineral nutrients from the weathering continental margins to shallow shelves, where marine life thrived.
