| Abstract [eng] |
The Telšiai deformation zone (TDZ) and the Drūkšiai-Polotsk deformation zone (DPDZ) in the crystalline basement of Lithuania are important structures, belonging to the wide Polotsk-Kurzeme fault belt in the western part of the East European Craton (EEC). Combining microstructural, metamorphic and isotopic geochronological information is a tool constraining the time of deformation and metamorphism in shear zones. The TDZ and DPDZ were reactivated several times in the Proterozoic and Phanerozoic times. Their correlation with similar deformation zones of the Baltic Shield in Sweden and Belarus provides new insights into the regional structure and evolution of the East European Craton around the Baltic Sea. |
