Distribution of apatite fission-track (AFT) cooling ages in Western Europe and northern Africa (a) based on a compilation of 5440 analyses (see Repository). Colored contour lines of AFT ages from the interpolation of individual dates in (a) based on 1000 km search radius. (c) Histogram with 10 Ma bins and Gaussian distribution (red) centered on the median with L1 scale of AFT age. (c) Minimum, quartiles Q1(25%) and Q3(75%), median and maximum of AFT data. Lines labeled 1 and 2 correspond to sections in Figure 15. TESZ: Trans-European Suture Zone.
