   Abstract : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. READ MORE

3. 2. Proterozoic hydrothermal alteration and mineralization along the Protogine Zone in southern Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Daniel Larsson; [1996]
   Keywords : geography; geology; Proterozoic hydrothermal alteration; mineralization; Protogine Zone; Sweden; Earth and Environmental Sciences;

   Abstract : Occurrences of high alumina rocks constituted by quartz, kyanite, rutile and Al-phosphates are spatially related with the Protogine Zone, a system of ductile and brittle deformation zones within the Proterozoic crust of southern Scandinavia. A hydrothermal origin has been proposed for high alumina rocks at Västanå, based on the chemistry of these rocks, while gradual transitions between magmatic rocks and high alumina rocks at Hökensås and Hålsjöberg suggest a similar origin.
