Fig. 8From: U–Pb geochronology of detrital zircons from a contact metamorphic Brixen Quartzphyllite (South-Tyrol, Italy): evidence for a complex pre-Variscan evolution of the Southalpine basementConcordia plot of detrital zircons illustrating the ages in the range of 638 ± 20 Ma. Fine lined ellipses represent data-point error and the thick lined ellipse is the error of the concordia diagram based upon all data of this specific age group. Sample FF3. The stipled line represents the interceptBack to article page
