  1. 16. Lower to Middle Ordovician carbonate sedimentology and stratigraphy of the Pakri peninsula, north-western Estonia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Niklas Brådenmark; [2016]
    Nyckelord :berggrundsgeologi; ordovicium; baltoskandiska grundhavet; havsnivå; kalksten; glaukonit hårdbottnar.; Earth and Environmental Sciences;

    Sammanfattning : Sedimentologi och stratigrafi från senaste tidiga ordovicium till och med mellanordovicium i nordvästra Estland har undersökts. Studien omfattar klippsektioner och Testepere stenbrott på Pakrihalvön, samt en vägskärning utanför staden Tabasalu strax väster om Tallinn. LÄS MER

  3. 17. A pre-LGM sandur deposit at Fiskarheden, NW Dalarna : sedimentology and glaciotectonic deformation

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anne-Cécile Flindt; [2016]
    Nyckelord :deformation; structures; sandur; glaciotectonic; glaciofluvial; fault-propagation fold; Earth and Environmental Sciences;

    Sammanfattning : The Fiskarheden quarry, situated in NW Dalarna, central Sweden, reveal thick deposits of coarse-grained sediments of Scott type facies association; a sandur deposited in an ice-proximal proglacial environment. Preliminary OSL dating of the sandur sediments suggest that they are of a pre-Saalian age (>200 000 years). LÄS MER

  4. 18. The late Holoce 14C reservoir age in the Chukchi Sea as inferred from tephra in marine sediments

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Aron Varhelyi; [2016]
    Nyckelord :Tephra; Aniakchak; Holocene; Chukchi Sea;

    Sammanfattning : Volcanic ash, or tephra, blankets the local and regional landscape following a volcanic eruption. If this ash layer is preserved and identified, it can act as a time synchronous marker bed (isochron) for correlation between marine, terrestrial, glacial and lacustrine deposits. LÄS MER

  5. 19. Paleontology and Sedimentology of the Alum Shale Formation at Björnberget, Västerbotten County, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Mannelqvist Alexander; [2016]
    Nyckelord :Brachiopoda; Acrotretida; New species; New locality; Alum Shale Formation; Brachiopoda; Acrotretida; ny art; ny lokal; Alunskifferformationen;

    Sammanfattning : A new locality of the Alum Shale Formation at Björnberget, Västerbotten County, of the lower allochthon of the Caledonian front is described herein. Two new species of acrotretid brachiopods were found. Tingitanella vilhelminia n. sp. LÄS MER

  7. 20. Sedimentology and carbon isotope stratigraphy of Lower–Middle Ordovician successions of Slemmestad (Oslo-Asker, Norway) and Brunflo (Jämtland, Sweden)

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Olof Peterffy; [2015]
    Nyckelord :Ordovician; carbon isotope stratigraphy; Baltoscandia; MDICE; ’Blommiga bladet’; ’Blodläget’; Earth and Environmental Sciences;

    Sammanfattning : Lower through Middle Ordovician strata are described with respect to sedimentology and carbon isotope stratigraphy from two areas, viz. two outcrops at Slemmestad in the Oslo-Asker district of southern Norway and a core section from the Brunflo area in Jämtland, central Sweden.
