Compilation of ages and KDE curves for Sn and W magmatic-hydrothermal mineralizing events, and RMGP emplacement, across the western part of the European Variscan belt including the FMC, as well as the Armorican and Iberian massifs. Most data are derived from U–Pb dating of cassiterite, wolframite, and columbite-group minerals. Bold symbols correspond to ages obtained from the Echassières magmatic complex. See Table S10 for data sources and references.
