    Abstract : The Baltic Sea is negatively affected by legacy pollutants such as metals and persistent organic pollutants (POPs) that are known to have adverse effects on living organisms, including, humans and were banned decades ago. This thesis addresses the dispersal of these pollutants from heavily contaminated, cellulose-rich sediments of industrial origin in the Ångermanälven river estuary in northern Sweden. READ MORE

  4. 2. Palaeobiology and Chemostratigraphy of the Precambrian - Cambrian Transitional Beds on the Siberian Platform

    Abstract : Biological innovations during the Precambrian-Cambrian transition opened evolutionary gates towards the modem biosphere. Two interrelated aspects of this process are investigated. The first one is the ecological radiation and beginning of calcareous biomineralization in mollusc-like organisms (shelled molluscs, coeloscleritophorans, and hyoliths). READ MORE

  5. 3. Volcanic stratigraphy, chemical stratigraphy, and hydrothermal alteration of the Petiknäs South Volcanic-hosted massive sulfide deposit, Sweden

    Author : Denis Schlatter; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The main exploration methods which have been used in the Skellefte district are prospecting for ore boulders in young glacial deposits and electrical geophysical methods. The discovery of new ores which likely are located at deep levels (>200 m), requires improved exploration methods, which in turn require a better understanding of the geology and alteration patterns of the known VMS deposits.
