  3. 37. Holocene environmental changes recorded by diatom stratigraphy in the southern Baltic Sea

    Författare :Elinor Andrén; Rick W. Batterbee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allmän och historisk geologi; General and Historical Geology;

    Sammanfattning : Sediment cores from the southern Baltic Sea and the Oder River estuary are analysed for their siliceous microfossil assemblages and organic carbon content. Long piston cores from the Bornholm and Gotland Basins provide data on the long-term Holocene history of the Baltic proper and serve as a natural background when evaluating the most recent environmental changes recorded in the short gravity cores.

  7. 40. Cretaceous dinoflagellate cyst stratigraphy of the Höllviken 1 well, Scania, Southern Sweden

    Författare :Helena Westin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main aim of this thesis was to develop an improved biostratigraphical subdivision for part of the Lower and Upper Cretaceous section (Albian to Santonian) of Scania, Southern Sweden. Earlier attempts at biostratigraphic zonation within the sequence Cenomanian to Coniacian based on other micro- and macrofossils have proven difficult due to an impoverished fauna. LÄS MER
