  2. 1. Provenance of the pre-Quaternary aeolian dust deposits of East Asia

    Author : Katja Bohm; Thomas Stevens; Anu Kaakinen; Alex Pullen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chinese Loess Plateau; Red Clay; mineral dust; sediment provenance; detrital zircon; detrital rutile; Neogene; Paleogene; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

    Abstract : Atmospheric mineral dust is a key component in the climate system, but its effect on and response to climate changes are poorly understood, especially over long timescales. This thesis investigates the sources of late Paleogene and Neogene dust deposits that formed under warmer-than-present global climates in the northern Chinese Loess Plateau (CLP) region in mid-latitude East Asia.

  4. 2. Palaeosurfaces and palaeovalleys on North Atlantic previously glaciated passive margins : reference forms for conclusions on uplift and erosion

    Author : Johan M. Bonow; Karna Lidmar-Bergström; Clas Hättestrand; Jens-Ove Näslund; Mats Olvmo; Adrian Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeosurface; palaeovalley; uplift; valley; incision; glacial erosion; weathering; Neogene; southern Norway; West Greenland; Earth sciences; Geovetenskap;

    Abstract : Palaeosurfaces and palaeovalleys are landforms under destruction in the present climate and/or tectonic regime, and thus mainly reflect processes not active today. Uplifted palaeosurfaces exist along the formerly glaciated passive continental margins around the North Atlantic. READ MORE

  5. 3. Eastern equatorial Pacific bulk sediment properties and paleoceanography since the late Neogene

    Author : Daniele Reghellin; Helen K. Coxall; Jan Backman; Gerald R. Dickens; Steve Hovan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoceanography; late Neogene; eastern equatorial Pacific; deep sea sediments; bulk sediment; stable isotopes; surface mixed layer; sediment physical properties; Marine Geology; maringeologi;

    Abstract : Reconstructing eastern equatorial Pacific (EEP) oceanography since the late Neogene (about 8 million years ago, Ma) is a central topic in current paleoceanographic investigations. The reason for this is two-fold. READ MORE

  6. 4. Neogene lacustrine deposits in the inland basins of northern Greece : stratigraphy, paleoenvironment, paleomagnetism and industrial usefulness

    Author : Panagiotis Kirittopoulos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Intensive tectonism in Neogene time created basins and mountain ranges in northern Greece with considerable topographic contrasts. The basins were successively filled with sediments up to a level of about +750 m. READ MORE

  7. 5. Paleoenvironmental significance of Baltic and North Atlantic late neogene benthic foraminifera

    Author : Otto Hermelin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is a summary of six previously published or submitted articles on (1) the significance of the geographic distribution of Recent benthic foraminifera in the Baltic Sea and the central North Atlantic, and (2) the significance of the stratigraphic distribution of Pliocene benthic foraminifera from the Blake Plateau, western North Atlantic.Recent benthic foraminifera in the Baltic Sea have a geographic distribution strongly correlated to the highly variable hydrographical conditions.
