Available at http://dx.doi.org/10.1016/j.palaeo.2013.02.004 The main objective of this thesis is to improve the knowledge on the depositional and environmental development of Svalbard during the Permian (299–252 Ma), with a primary focus on the Early to Late Permian Kapp Starostin Formation (Tempelfjorden Group). Thirteen localities of Permian sedimentary strata were investigated with respect to their sedimentological and geochemical properties. Sediments from this period reflect mostly marine deposition on a broad epicontinental shelf at the northern margin of the supercontinent Pangea. Sedimentary facies reveal distinct changes in depositional environment, from marginal/restricted marine settings in a warm and dry climate, to a temperate to cold-water, open-marine shelf. The latter is characterized by cool-water biota including brachiopods, echinoderms, bryozoans and siliceous sponges. These sedimentological shifts are related to a number of controlling factors including changes in palaeolatitude, ocean circulation and upwelling, global climate, and sea level changes. A sequence ...
