Radial plots, track length histograms, AFT single grain ages versus track length and Dpar (only for fault rock samples) of AFT single grain ages. Radial plots (Galbraith 1990) show the precision of the individual grain ages along the x-axis (precision increasing to the right). All three fault core samples are characterized by two age components (marked) where the single grain ages from the younger age components range between 12.8 and 3.6 Ma. FC fault core, DZ damage zone, HR host rock. For location of sampled drilling sites, see Fig. 2. The original data as well as radial plots for FC samples and Dpar were published by Wölfler et al. (2010), track length histograms and radial plots for HR and DZ samples are added here
