1. 21. Upper Ordovician through lowermost Silurian stratigraphy and facies of the Borenshult-1 core, Östergötland, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Amir Noor; [2010]
   Keywords : Borenshult-1 core; palaeoclimate; upper Ordovician; sea-level; GICE; HICE; Baltoscandia; Earth and Environmental Sciences;

   Abstract : The Ordovician is an important period in the Phanerozoic, with remarkable faunal turnovers, several major carbon isotope excursions, and shifting climate. The strata of this time period not only re-veal these events but also provide useful information about the palaeoclimate and sea-level. READ MORE

3. 22. Changes in beyrichiid ostracode faunas during the Late Silurian Lau Event on Gotland, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Rebecka Rääf; [2010]
   Keywords : Gotland; Late Silurian; Lau Event; ostracodes; Beyrichiidae; faunal turnovers; Sensilur; Laukatastrofen; ostrakoder; beyrichiider; faunaförändringar; Earth and Environmental Sciences;

   Abstract : This paper deals with how palaeocope ostracodes of the family Beyrichiidae, from the Silurian strata at Gotland were affected by the Late Silurian Lau Event. The Lau Event is associated with a positive carbon isotope excursion, lithology changes and faunal changes in accumulated strata related to sea-level changes and a glaciation in the Late Ludlow.

4. 23. The spore record of early land plants from upper Silurian strata in Klinta 1 well, Skåne, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Kristina Mehlqvist; [2009]
   Keywords : Silurian; spores; flora; palynology; Klinta 1 drillcore; silur; sporer; palynologi; Klinta borrkärna 1; Earth and Environmental Sciences;

   Abstract : Prover från Öved-Ramsåsagruppen i Skåne från övre Silur har undersökts palynologiskt, främst med avseende på sporer från landväxter. Sedimenten består av karbonater med silisiklastiskt innehåll och paleomiljön har tolkats till ett strandnära marint ekosystem. READ MORE

5. 24. Brachiopod faunal dynamics during the Silurian Ireviken Event, Gotland, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Åsa Erlfeldt; [2006]
   Keywords : Ireviken Event; brachiopods; Lilliput; Silurian; Gotland; Lower Visby Formation; Upper Visby Formation; brachiopoder; Silur; Undre Visbyformationen; Övre Visbyformationen; Earth and Environmental Sciences;

   Abstract : The brachiopod fauna from parts of the Lower and Upper Visby formations on Gotland has been investigated through a combined outcrop and literature study. The strata of these formations were formed during the Ireviken Event, one of the severest identified oceanic events on Gotland, with diversity changes and extinctions among several groups of marine taxa.

6. 25. Sedimentary facies and fauna of the Late Silurian Bjärsjölagård Limestone Member (Klinta Formation), Skåne, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Abstract : Bjärsjölagårdkalkstenen i Skåne, södra Sverige, är av sen ludlowålder och utgör en del av Klintaformationen inom Öved-Ramsåsagruppen. Denna kalksten bildades under tiden för den globalt kända Laukatastrofen och ett kraftigt havsnivåfall i den Baltiska bassängen. READ MORE
