1. 6. Depositional history of the Neoproterozoic Visingsö Group, south-central Sweden

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Viktor Ahrenstedt; [2017]
   Nyckelord :sedimentology; depositional history; Visingsö Group; Neoproterozoic; Earth and Environmental Sciences;

   Sammanfattning : 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. 7. Ice advance-retreat sediment successions along the Logata River, Taymyr Peninsula, Arctic Siberia

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Martin Bernhardson; [2013]
   Nyckelord :Sibirien; Tajmyrhalvön; Weichselian glaciation; Ice advance-retreat stages; Russia; Taymyr Peninsula; Siberia; Ryssland; isframstötar-isreträtter; Weichselistiden; Earth and Environmental Sciences;

   Sammanfattning : A number of sites were investigated in river sections along the Logata River on the Taymyr Peninsula, Russia, and its adjacent areas to shed more light on the glaciation history over the last glacial cycles. The sediments exposed at the investigated sites are correlated and put into a local stratigraphic scheme divided into five main units. LÄS MER

4. 8. Stratigraphy, facies and depositional history of the Colonus Shale Trough, Skåne, southern Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Magnus Eriksson; [2012]
   Nyckelord :Sweden; tec-tonic subsidence; gamma ray; backstripping; Lower Palaeozoic; Colonus Shale Trough; Sorgenfrei-Tornquist Zone; Colonustråget; Sorgenfrei-Tornquistzonen; underpaleozoikum; tektonisk subsidens; Sverige; Earth and Environmental Sciences;

   Sammanfattning : Colonustråget är en viktig tektonisk enhet i den s.k. Sorgenfrei-Tornquistzonen i Skåne, södra Sverige. Den sedimentära sekvensen består av en kambrisk till silurisk succession dominerad av finkorniga klas-tiska sediment samt en mindre del kalksten. LÄS MER

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

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Ahmed Salah Badawy; [2012]
   Nyckelord :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;

   Sammanfattning : 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.

7. 10. Lövestads åsar : en isälvsavlagring bildad vid inlandsisens kant i Weichsels slutskede

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Ingrid Flodhammar; [2011]
   Nyckelord :Lövestad; åsar; isälvsmaterial; Skåne; nedisningshistoria; glaciofluvial deposit; esker; Scania; history of Weichselian; Earth and Environmental Sciences;

   Sammanfattning : The Lövestad ridges are a glaciofluvial deposit located in south eastern Scania. The deposits and how they were formed have been studied. LÄS MER
