1. 1. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

   Sammanfattning : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny. LÄS MER

3. 2. Autolytinae: molecules, morphology, and reproduction

   Sammanfattning : Autolytines constitute a well delineated group of syllid polychaetes, separated from other syllids by the presence of a sinuous pharynx, lack of ventral cirri and reproduction with dimorphic sexes. The group comprises c. 170 nominal species distributed worldwide, mostly inhabiting hard substrates restricted to the continental shelf. LÄS MER
