  2. 1. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea

    Author : Marloes Kortekaas; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kartografi; klimatologi; Geofysik; fysisk oceanografi; physical oceanography; meteorology; Sedimentologi; Stratigrafi; Stratigraphy; Baltic Sea; geokemi; Petrologi; mineralogi; geochemistry; mineralogy; Petrology; greigite; mineral magnetics; sea-level changes; Holocene; Littorina transgression; geomorphology; pedology; cartography; climatology; meteorologi; Geophysics; Sedimentology; Optically Stimulated Luminescence OSL ; Fysisk geografi; geomorfologi; marklära; Physical geography;

    Abstract : 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. READ MORE

  4. 2. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Author : Shiyong Yu; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Abstract : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. READ MORE

  5. 3. Climate influenced deposition on a low latitude Sheinwoodian carbonate ramp, Gotland, Sweden

    Author : Mikael Jacobsson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gotland; tempestites; cyclicity; orbital forcing; Sheinwoodian; Silurian; Wenlockian; Sedimentology; Sedimentologi;

    Abstract : The Sheinwoodian succession of Gotland comprises the Högklint, Tofta and Hangvar Formations and most of the Slite Group. The succession consists of hierarchically ordered shallow marine depositional cycles, produced by orbitally forced climate changes. READ MORE

  6. 4. Past environment and sediment dynamics in the Black Sea-Caspian Sea region from Southern Russian loess sequences

    Author : Chiara Amalia Költringer; Thomas Stevens; Bjarne Almqvist; Ian Snowball; Kathryn Fitzsimmons; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Loess deposits are excellent past climate and environment archives and contain records of aeolian mineral dust accumulation. Loess deposits stretch across Eurasia and sequences along the Lower Volga in the Northern Caspian lowland in the South East European Plain represent a key link between European and Asian loess.

  7. 5. Late Ordovician-Early Silurian facies development and stratigraphy of Jämtland, central Sweden

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

    Abstract : 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).
