    Author : Lena Gustavsson; [2005]
    Keywords : geography; geology; Late Silurian; Lau Event; brachiopods; Gotland; Sweden; Earth and Environmental Sciences;

    Abstract : The impact of the Ludfordian Lau Primo-Secundo Event on brachiopods from Gotland has been investigated. About 12 000 individuals were identified from five samples. The results are supplemented by an extensive literature study. On Gotland, the Lau Event spans the Botvide Mbr (uppermost När Fm, upper Hemse Group) and the Eke Fm. READ MORE

  3. 32. A comparative study between loss on ignition and total carbon analysis on Late Glacial sediments from Atteköps mosse, southwestern Sweden, and their tentative correlation with the GRIP event stratigraphy

    University essay from Lunds universitet/Geologiska institutionen

    Author : Daniel-Stefan Veres; [2001]
    Keywords : Atteköps mosse; limnic sediments; Late Glacial; loss on ignition; total carbon; Earth and Environmental Sciences;

    Abstract : Popular abstract: In this study, several sediment core from Atteköps mosse, southwestern Sweden, were investigated with respect to lithostratigraphy, loss on ignition analysis, grain size distribution, magnetic susceptibility, total carbon analysis and 14C dating. The first part of the study foccuses on a detailed analysis of the above mentioned sediment parameters. READ MORE

    Abstract : Halysitid corals from the Llandoverian (Early Silurian) Berge Limestone Formation in Jämtland, central Sweden, are described. The investigation of the halysitid corals was done on material derived from the Norderön Island in Lake Storsjön, central Sweden. READ MORE

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

    University essay from Lunds universitet/Geologiska institutionen

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

    Abstract : 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. READ MORE
