Abstract
Microstructural and microprobe studies of a staurolite-garnet-sillimanite-biotite schist indicate a peak of metamorphism syntectonic with a third phase of folding in a regional polyphase deformational history. Metamorphic conditions are calculated to be 675 ± 25°C and 500± 25 MPa (5.0± 0.25 kbar) with PH2O = 0.6 Ptot. The implications of such a late peak of metamorphism in this part of the Svecokarelides are assessed.Keywords
