  1. 16. Krossbergskvalitet och petrografi i den kambriska Hardebergasandstenen i Skåne

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Cecilia Jansson; [2005]
    Nyckelord :sandstone; petrography; technical properties; strength; Cambrian; Hardeberga; Scania; Sweden; sandsten; krossberg; petrografi; hållfasthet; bergkvalitet; kambrium; Skåne; Sverige; Earth and Environmental Sciences;

    Sammanfattning : The Lower Cambrian Hardeberga Sandstone Formation of Scania, southern Sweden, consists of a basal arkosic sandstone unit, overlain by three vertically stacked, shallowing-upward sequences. These three sequences consist predominantly of light grey or whitish, quartz-arenitic sandstones deposited in shallow marine environments. LÄS MER

  3. 17. Early to early Middle Ordovician conodont biostratigraphy of the Tamsalu drill core, central Estonia

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Lisa Sjöstrand; [2003]
    Nyckelord :Ordovician; Latorpian; Volkhovian; Kundan; Aserian; conodonts; biostratigraphy; Parapaltodus n. sp. A; Texania sp. A; Tamsalu; Estonia; Earth and Environmental Sciences;

    Sammanfattning : This investigation examines the distribution of conodont elements in the Early to early Middle Ordovician Latorpian, Volkhovian, Kundan and Aserian stages of the Tamsalu drill core in central Estonia. Slightly more than 24, 600 conodont elements from 17 samples were examined, and the biostratigraphic results were compared to previous works on conodont biostratigraphy from localities in Estonia, Russia and Öland, Sweden.

  4. 18. Jämförande litologisk och geokemisk studie av Sevens amfibolitkomplex i Sylarna och Kebnekaise

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ann Pettersson; [2003]
    Nyckelord :geografi; geologi; litologi; geokemi; Sevens amfibolitkomplex; Sylarna; Kebnekaise; Earth and Environmental Sciences;

    Sammanfattning : Sevekomplexet är ett 900 km långt och volymmässigt dominerande inslag i den övre skollberggrunden i de Skandinaviska Kaledoniderna. Komplexet representerar delar av Balticas passiva kontinentkant och havet strax utanför. Litologin domineras av metabasiter. Om dessa tillhör en och samma magmatiska händelse, representerar de en s.

  5. 19. Petrografi och diagenes i den underkambriska lagerföljden i Skrylle, Skåne

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Imre Molnos; [2002]
    Nyckelord :petrografi; diagenes; facies; sandsten; kvartscementering; styloliter; underkambrium; Skrylle; Skåne; Earth and Environmental Sciences;

    Sammanfattning : The Lower Cambrian of Scandinavia consists mainly of light-coloured marine sandstones, with thicknesses reaching approximately 120 m in Skåne (Scania). Two drill cores from the Skrylle Quarry of west-central Skåne were investigated and documented with respect to their petrographic properties, mineral contents, and diagenetic history. LÄS MER

  7. 20. Diagenetic and petrophysical properties of deeply versus moderately buried Cambrian sandstones of the Caledonian foreland, southern Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Christine Karlsson; [2001]
    Nyckelord :diagenesis; petrography; sandstone; burial; Lower Cambrian; Caledonian foreland; Västergötland; Skåne; Sweden; Earth and Environmental Sciences;

    Sammanfattning : The Lower Cambrian strata of the Caledonian foreland of southern Sweden consist mainly of quartzitic sandstones with thicknesses of approximately 35 meters in Västergötland and 120 meters in Skåne. In the distal, moderately buried western members of the File Haidar Formation of Västergötand porosity and permeability was higher than in the proximal deeply buried units of the Hardeberga Formation of Skåne.
