  1. 16. Climatic signals and frequencies in the Swedish Time Scale, River Ångermanälven, Central Sweden

    Author : Mikkel Sander; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; klimatologi; pedology; cartography; climatology; Fysisk geografi; geomorfologi; geomorphology; Physical geography; winter precipitation; climate change; central Sweden; last 2000 year; discharge; varve;

    Abstract : Any future climate variation forced by human activities will be superimposed on the background of natural climate variation. Therefore, before interpreting the present climate and addressing future climate scenarios some knowledge of past climate is necessary. READ MORE

  2. 17. Stratigraphy and facies of Middle Silurian epicontinental carbonate platform deposits of Gotland, Sweden

    Author : Mikael Calner; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysisk geografi; Geologi; Geology; physical geography;

    Abstract : The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of these deposits.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

    Abstract : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. READ MORE

  4. 19. The origin of iron ores in Bergslagen, Sweden, and their relationships with polymetallic sulphide ores

    Author : Nils Jansson; Paul Spry; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Bergslagen mining district of southern Sweden is one of Europe’s classic mining districts with more than 1 000 years of mining history. One of the typical features of Bergslagen is a spatial association between Zn-Pb-Ag-(Cu-Au) sulphide deposits and magnetite-rich Fe oxide deposits. READ MORE

  5. 20. Geophysical investigation for 3D geological modelling and ore exploration in the Skellefte mining district

    Author : Saman Tavakoli; Thorkild Rasmussen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : The Skellefte mining district, northern Sweden, is regarded as one of the country’s richest mineral districts. Most of the outcropping deposits in this district or those deposits which are located at shallow depths (≤ 300 m) are likely to have already been discovered, which motivated the Swedish mining companies to expand their explorations at greater depths (e.
