Timing of ductile shearing within the Druksiai-Polotsk Deformation Zone, Lithuania: a U-Pb titanite age
A U-Pb dating of titanite from an augen granitoid mylonite in the Druksiai-Polotsk Deformation Zone has yielded a concordant age of 1534 +/- 9 Ma. This light brown titanite follows the foliation in the host rock and was obviously formed during retrogression from amphibolite to epidote-amphibolite facies and coeval mylonitization. Shear zones of the same age are known in southern and central Sweden
