   Abstract : Den viktigaste tektoniska strukturen i Blekinge-Bornholm Provinsen (BBP), i sydost Blekinge, är den s.k. Småland-Blekinge Deformationszonen (SBDZ). Denna zon har en ungefärlig ost-västlig orientering och separerar Smålandsgranitoiderna, tillhörande TIB i norr från Tvingsgranitoider (graniter, granodioriter, tonaliter) i söder. READ MORE

5. 4. Retrograded eclogites of the Richarddalen Complex, NW Svalbard : petrology and P/T-conditions

   University essay from Lunds universitet/Geologiska institutionen

   Author : Ros-Mari Hesbøl; [1996]
   Keywords : Svalbard; geography; geology; retrograded eclogites; Richarddalen Complex; petrology; P T-conditions; Earth and Environmental Sciences;

   Abstract : At least three terranes have been identified in the Svalbard Caledonides, each one having independent structures and tectonothermal evolution. On Biskayerhalvöya in the Northwestern Terrane, eclogites, located within deformed igneous basement rocks, have been dated by the U-Pb zircon method to c. 625 Ma. READ MORE
