    Author : Vivi Vajda; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleobotanik; phylogeny; Palaeobotany; Cingutriletes scanicus sp. nov; Palynology; palynofacies; paleovegetation; transgression; Early Cretaceous; Cenomanian; Turonian; Bornholm; Denmark; Sweden; Scania; fylogeni; palynologi; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : A palynological investigation of Cretaceous sequences from Höllviken 2, Svedala 1 and Norrevång 1 wells of Scania, Southern Sweden, and from the Arnager Greensand-Arnager Limestone transition on the island of Bornholm, Denmark, was conducted. Well preserved palynofloras were found in strata consisting of shaly mudstones, glauconitic sandstones (greensand) and limestone. READ MORE

  4. 2. Cretaceous dinoflagellate cyst stratigraphy of the Höllviken 1 well, Scania, Southern Sweden

    Author : Helena Westin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  5. 3. Big survivors with small flowers : Fossil history and evolution of Laurales and Chloranthaceae

    Author : Helena Eklund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; systematisk botanik; Systematic Botany;

    Abstract : This thesis provides palaeobotanical evidence on Cretaceous Laurales and Chloranthaceae, and discusses and evaluates the material in a phylogenetic framework. Chloranthaceae extend back to the Barremian or Aptian and Laurales to the Albian (both Early Cretaceous). READ MORE

  6. 4. Seismic stratigraphy and tectonics offshore Scania, south-western Baltic Sea

    Author : Wasim Paracha; Boris Winterhalter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Abstract : Geophysical data and descriptions of deep wells, produced during hydrocarbon explorations in the south-western part of the Baltic Sea offshore Scania, have revealed new information on the geological development of the area. This investigation is concentrated to the offshore triangular segment between the northwest-southeast Permian Sorgenfrei-Tornquist Zone through Scania and the east-west Caledonian Front north of Rügen.
