1. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

2. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The goal of this study was to identify and describe different microstructures observed in samples from two major shear zones in the Gällivare area, namely the Nautanen Deformation Zone (NDZ), and the Fjällåsen deformation zone (FDZ). Thirteen samples were examined during this study. READ MORE

3. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : 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. READ MORE

4. U-Pb geochronology and geochemistry of host rocks to the Bastnäs-type REE mineralization in the Riddarhyttan area, west central Bergslagen, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : 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. READ MORE

5. The copper sulphide mineralization of the Zinkgruvan Deposit, Bergslagen, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : At Zinkgruvan, Sweden, zinc, lead and silver are mined from a stratiform ore body. It is considered syngenetic and situated in metavolcanic and metasedimentary rocks. A fault, the Knalla fault, separates the Zinkgruvan deposit into two parts. READ MORE
