    Abstract : The Palaeoproterozoic Dannemora inlier is situated in the north-eastern Bergslagen region. The inlier consists of primary and reworked volcanic deposits, stromatolitic limestone and skarn that have been subjected to upper greenschist facies metamorphism. READ MORE

  4. 2. Lake sedimentary archives of medieval mining and smelting in Sweden : tracking environmental changes from site to landscape

    Author : Erik Myrstener; Richard Bindler; Christian Bigler; Elinor Andrén; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; environmental science; miljövetenskap;

    Abstract : While the environmental impact of the industrial age is massive, including climate change, pollution, microplastics and habitat loss, our influence reaches further back than many recognize. In Sweden, an early and important activity with large potential impact was the mining and smelting of iron, copper and silver ores over the last ~800 years. READ MORE

  5. 3. The tectonic evolution of the western part of the Svecofennian orogen, central Sweden : Insight from U/Pb and 40Ar/39Ar geochronology at Forsmark

    Abstract : The Forsmark area, in the western part of the Svecofennian orogen, central Sweden, is situated between two major Palaeoproterozoic tectonic domains that show contrasting histories with respect to timing of igneous activity, ductile deformation and metamorphism. At Forsmark, WNW to NW trending, ductile deformation belts anastomose around tectonic lenses with an inferred lower degree of ductile strain. READ MORE
