1. 1. Impactites from the Hiawatha crater, North-West Greenland

   Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

   Författare :Jacob Gustafsson; [2020]
   Nyckelord :Hiawatha; impact crater; Cape York; Baffin Bay; Greenland Ice Sheet; Younger Dryas; meteorite; impactite; organic carbon; conifer; vitrinite reflectance; Ro; cellular texture; chromite; chromium isotope; toasted quartz; ballen quartz; melted carbonate; granular zircon; planar deformation feature;

   Sammanfattning : The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. LÄS MER

3. 2. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

   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
