  1. 21. Deformation, metamorphism and remobilisation in the Hornkullen polymetallic deposit, western Bergslagen, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Stefan Andersson; [2014]
    Keywords : ore genesis; Bergslagen; deformation; remobilisation; metamorphism; geothermobarometry; malmbildning; Bergslagen; deformation; ommobilisering; metamorfos; geotermobarometri;

    Abstract : The polymetallic Hornkullen deposit is situated in the western part of the Bergslagen ore province, Sweden. It is hosted by an inlier of approximately 1.90-1.88 Ga Svecofennian volcanic and sedimentary metasupracrustal rocks enclosed in a significantly younger, c. READ MORE

  3. 22. The Kalgoorlie gold : a review of factors of formation for a giant gold deposit

    University essay from Lunds universitet/Geologiska institutionen

    Author : Wayne Fullerton; [2013]
    Keywords : Kalgoorlie; Yilgarn; gold; mineralisation; Earth and Environmental Sciences;

    Abstract : The Archaean Yilgarn craton in Western Australia is a granite greenstone belt with abundant economically important mineral reserves, including several world-class gold deposits such as the giant Kalgoorlie deposit. Structural controls on gold deposition and the fact that most deposits were formed later in the craton’s tectonic history, has resulted in the general acceptance of a late-orogenic structurally-controlled model for gold mineralization in the Yilgarn craton.

  4. 23. The mineral composition of the Burkland Cu-sulphide deposit at Zinkgruvan, Sweden : a supplementary study

    University essay from Lunds universitet/Geologiska institutionen

    Author : Christine Andersen; [2009]
    Keywords : Zinkgruvan; Bergslagen; Åmmeberg-deposit; Burkland Cu-mineralisation; chalcopyrite; hydrothermalcopper sulphide; VMS; SEDEX copper sulphide; SEDEX; Åmmeberg-malmförekomst; Burkland kopparmineralisering; kopparkis; hydrotermal kopparsulfid; Earth and Environmental Sciences;

    Abstract : The Zinkgruvan Mining AB, situated in south-central Sweden in Örebro County, south-east of Åmmeberg, plans to expand their production on a massive, carbonate hosted copper-sulphide ore deposit, the Burkland Cu-mineralization in the eastern part of Knalla. At present mainly Zn-Pb-Ag are mined. READ MORE

  5. 24. Agro ecosystems in a changing climate : adaption through crop rotations

    University essay from SLU/Horticulture

    Author : Tora Råberg; [2008]
    Keywords : climate change; crop rotation; agro ecosystem; vegetation period; biodiversity; soil erosion; leaching of nutrients; CO2; temperature; precipitation; water stress; draught; mineralisation; weeds; pest; windbreaks; disease;

    Abstract : Climate change is a phenomenon that affects everyone. It is thus of high relevance to gain knowledge in how the farms that supply society with food will be affected and what adaptations can be made to minimise negative effects on field level. READ MORE

  6. 25. The impact of agroforestry and other landuses on soil functional capacity

    University essay from SLU/Dept. of Ecology

    Author : Lena Adolfsson; [2008]
    Keywords : agroforestry; soil functional capacity; Biolog Ecoplate; substrate utilisation potential; soil microorganism; functional biodiversity; soil bacteria;

    Abstract : Deforestation, agricultural cultivation and overuse of land resources can lead to decreasing functional capacity of soil microorganisms, e.g. decreasing decomposition and mineralisation capacity and rate. READ MORE
