  1. 1. Loess in southwestern Sweden. Determining the genesis of the silt-rich layer rödfemman in Svartedalen nature reserve

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fanny Ekström; Anna Hedeving; [2021-10-28]
    Nyckelord :Loess; silt; grain-size distribution; bimodal; Optically Stimulated Luminescence OSL ; p-XRF; spatial distribution; paleowind;

    Sammanfattning : The presence of loess in Sweden is relatively unexplored and has only been found in a few places. Loess acts as a paleoclimatic proxy, which in times of changing climates, is highly relevant. LÄS MER

  3. 2. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pelle Kronborg; [2020]
    Nyckelord :loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Sammanfattning : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. LÄS MER

  4. 3. En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur

    Magister-uppsats, Lunds universitet/Arkeologi

    Författare :Nina Petersson; [2007]
    Nyckelord :Tafonomi; Tafonomiska processer; Mesolitikum; Neolitikum; Anläggningar; Gravläggningar; Offer; Archaeology; Arkeologi; History and Archaeology;

    Sammanfattning : This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. LÄS MER

  5. 4. Trace fossils from the Paleocene-Middle Eocene Monte Sporno flysch complex, northern Apennines, Italy

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hanna Calner; [1996]
    Nyckelord :Flysch deposits; trace fossils; Zoophycos; Chondrites; Helminthoida labyrinthica; Taphrhelminthopsis; Nereites ichnofacies; pre-depositional; postdepositional; Monte Sporno; Northern Apennines; Italy; Earth and Environmental Sciences;

    Sammanfattning : The trace fossil assemblages exposed at the Armorano road section in the Monte Sporno unit, Northern Apennines, Italy, occur in a turbidite sequence composed of fine-grained limestones (mudstones) and argillaceous limestones (wackestones) together with coarser grained calcareous sandstones and claystones, both turbiditic and hemipelagic. Fodinichnial vertical burrows of post-depositional origin and pascichnial horizontal trails of pre-depositional origin alternates depending on lithology. LÄS MER
