  6. 5. Compositional Systematics of Sphalerites from Western Bergslagen, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aristeidis Kritikos; [2016]
    Keywords : Western Bergslagen; sphalerite; critical elements; trace elements; substitution mechanisms; EMPA; LA-ICP-MS; Västra Bergslagen; zinkblände; kritiska metaller; spårelement; substitutionsmekanismer; EMPA; LA-ICP-MS;

    Abstract : Sphalerite is, apart from being the main global source of zinc (Zn), also one of the main source for the critical elements indium (In), gallium (Ga) and germanium (Ge), which can be extracted as by-products during Zn mining. In the westernmost part of the Palaeoproterozoic Bergslagen ore province, Sweden, In-anomalies have been reported from sulphide mineralizations. READ MORE
