  1. 1. The lower and middle Cambrian of Sweden: trilobites, biostratigraphy and intercontinental correlation

    Författare :Niklas Axheimer; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Paleontologi; Palaeontology; fysisk geografi; Geologi; physical geography; Geology; Sweden; correlation; trilobites; biostratigraphy; Cambrian; Sedimentology;

    Sammanfattning : This thesis is based on studies of Cambrian successions in Sweden, with particular focus on the middle Cambrian biostratigraphy and its correlative relationship to the proposed global agnostoid zonation. The investigated material, mainly trilobites, was collected from both outcrops and drill cores from five provinces in Sweden: Skåne (Scania), Öland, Västergötland, Jämtland and Lapland. LÄS MER

  3. 2. Late Ordovician-Early Silurian facies development and stratigraphy of Jämtland, central Sweden

    Författare :Peter Dahlqvist; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biostratigraphy; Sedimentology; Stratigrafi; Stratigraphy; Paleontologi; Palaeontology; Jämtland; provenance; brachiopods; conodonts; Hirnantian; Silurian; Ordovician; glaciation; eustasy; Sedimentologi; sedimentology;

    Sammanfattning : This thesis is based on studies of Lower Palaeozoic sedimentary successions within the central Scandinavian Caledonides. These deposits have been transported by considerable nappe displacement (several kilometres), and are today relatively isolated from the nearest coeval outcrops (Dalarna 250 km, Oslo Region 350 km).

  5. 4. Middle and Upper Ordovician graptolites, trilobites, and biostratigraphy of Scania and Jämtland, Sweden

    Författare :Christian Pålsson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; Sweden; Jämtland; Scania Skåne ; Upper Ordovician; Middle Ordovician; palaeoecology; biostratigraphy; lithostratigraphy; Graptolites; trilobites; Geologi; fysisk geografi; Palaeontology; Paleontologi;

    Sammanfattning : Graptolites and some trilobites from Middle–Upper Ordovician siliciclastic and calcareous rocks in Scania (Skåne), southern Sweden, and Jämtland, central Sweden, are described and discussed. Their stratigraphic distribution is discussed on the basis of new and old collections from outcrops and drill cores. LÄS MER

  7. 5. Jurassic and Early Cretaceous selachians - focus on southern Scandinavia

    Författare :Jan Rees; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geology; Paleontologi; Palaeontology; Lissodus; palaeoecology; England; Denmark; Sweden; sharks; selachians; Jurassic; Early Cretaceous; physical geography; Geologi; fysisk geografi;

    Sammanfattning : The Jurassic and Early Cretaceous selachian faunas of Scania (Skåne), southern Sweden and the island of Bornholm (Denmark) have been investigated. Three Early Jurassic shark tooth assemblages have been recorded and investigated, one from Hettangian strata and the other two from Pliensbachian sediments. LÄS MER
