  2. 11. Sediment sources and transport pathways, Lithuanian coastal zone

    Author : Milda Kairytè; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

    Abstract : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. READ MORE

  4. 12. The tectonic evolution of northwest Svalbard

    Author : Carl Henrik Pettersson; Victoria Pease; Robert Strachan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Svalbard; Rodinia; Laurentia; Zircon; Provenance; Migmatites; Clockwise P-T; Solid earth geology and petrology; Berggrundsgeologi och petrologi; Geology; geologi;

    Abstract : Svalbard represents the uplifted and exhumed northwest corner of the Barents Sea Shelf. Pre-Carboniferous rocks of Svalbard are divided into the Eastern, Northwestern and Southwestern Terranes, were amalgamated during the Caledonian Orogen and are separated by north-south-trending strike-slip faults.

    Abstract : The visual exploration of large and complex network structures remains a challenge for many application fields, such as systems biology or social sciences. Often, various domain experts would like to work together to improve the analysis time or the quality of the analysis results. READ MORE

  7. 15. 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.
