   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Dino Leopardi; [2020]
   Nyckelord :Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

   Sammanfattning : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. LÄS MER

3. 2. U-Pb geochronology and geochemistry of host rocks to the Bastnäs-type REE mineralization in the Riddarhyttan area, west central Bergslagen, Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Wictor Linders; [2016]
   Nyckelord :Riddarhyttan; REE; Metavolcanic rocks; LA-ICP-MS; Zircon; Monazite.; Earth and Environmental Sciences;

   Sammanfattning : The geochronology of felsic metavolcanic rocks hosting the Bastnäs-type rare earth element (REE) mineralization in the Riddarhyttan area in the Bergslagen region, Sweden, was investigated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Th-Pb on zircon and monazite. U-Pb data from four host rock samples yield dates of 1899 ± 4 Ma (MSWD=2. LÄS MER
