Here we present published and new age data of plutonic and volcanic rocks from Saxothuringia obtained by the high-precision CA-ID-TIMS U-Pb zircon dating method. This method has an uncertainty of ca. 0.1-0.2 % (corresponding to < ± 0.5 Ma) that is ca. 10 times smaller than all other recently established dating methods. Consequently, the application of this method allows better establish the exact sequence of magmatic processes in time and space. We show that magmatism in the Erzgebirge and in the Lausitz mainly occurred during two larger magmatic phases and that volcanic rocks first appeared in the Eastern Erzgebirge. We present also dating results from several volcano-sedimentary basins in Saxothuringia that allows a better comparison of their temporal evolution.
