1. Event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden
Sammanfattning : This thesis outlines an event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden. Events are short-lived occurrences that have left traces in the geological record and which, therefore, may be used for correlation and inter-regional comparisons. LÄS MER
2. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea
Sammanfattning : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. LÄS MER
3. Late Quaternary palaeoecological event stratigraphy in the Horton Plains, central Sri Lanka : with contributions to the recent pollen flora
Sammanfattning : .... LÄS MER
4. Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden
Sammanfattning : Three sites, Torreberga in Skåne, Farslycke in Blekinge and Lake Bolmen in Småland, with Late Weichselian lake sediments were studied with respect to pollen analysis and palaeomagnetism. The chronologies are based on pollen stratigraphical correlations, radiocarbon dating and, for two of the sites, on a clay-varve chronology. LÄS MER
5. Silurian Carbonate Platforms of Gotland, Sweden - Archives of Local, Regional and Global Environmental Changes
Sammanfattning : This thesis treats the Silurian carbonate platforms of Gotland, Sweden, which formed close to the equator within the East Baltic Basin. Three different time intervals, all involving changes in facies composition and structure of the platforms, have been studied; Late Homerian, latest Homerian ? earliest Gorstian, and late Ludfordian, respectively.
