  1. 1. A palynological study across the Ordovician Kinnekulle bentonite, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johan Nordas; [2015]
    Keywords : Acritarch; bentonite; Ordovician; Borenshult-1; Sweden; Kinnekulle; Earth and Environmental Sciences;

    Abstract : A palynological analysis across the Ordovician (Sandbian) Kinnekulle bentonites in south Central Sweden has been performed. The sedimentary successions were recovered from the Borenshult -1 drillcore in the Motala area, south central Sweden. The lithology is dominated by mudstones and two thick bentonite beds. READ MORE

  3. 2. The fossil wonders of the Silurian Eramosa Lagerstätte of Canada : the jawed polychaete faunas

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jesper Härling; [2012]
    Keywords : scolecodonter; polychaeter; silur; palaeobiogeography; palaeoecology; Silurian; Eramosa Lagerstätte; scolecodonts; polychaete faunas; paleoekologi; paleobiogeografi.; Earth and Environmental Sciences;

    Abstract : The Silurian Eramosa Lagerstätte in Ontario, Canada, is represented by three distinguished biotas (1 to 3) with exceptionally well preserved fossils. In this study, the jawed polychaete fauna is described and discussed for the first time, on the basis of scolecodonts and jaw apparatuses, recovered from Biota 1 and 3. READ MORE

  4. 3. Sequence stratigraphy, palynology and biostratigraphy across the Ordovician-Silurian boundary in the Röstånga-1 core, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ahmed Salah Badawy; [2012]
    Keywords : avsättningsmiljöer; stratigrafi; Sweden; Scania; Röstånga; Silurian; Ordovician; TAI; Thermal Alteration Index; palynology; sea level changes; stratigraphy; depositional environments; havsnivåförändringar; palynologi; Ordovicium; Silur; Skåne; Sverige.; Earth and Environmental Sciences;

    Abstract : A multiproxy study on sedimentary rocks spanning the Ordovician-Silurian boundary has been performed on material from the Röstånga-1 core, with the aims to improve the biostratigraphical and sedimentological framework and to interpret the depositional environment during this interval in Earth’s history. The sedimentary succession in the Röstånga-1 core is developed in the Scanian Lithofacies Belt and is considered an excellent upper Middle Ordovician-Lower Silurian reference section for southernmost Sweden.
