Popis | Zircons from durbachite and syenite samples, from Třebíč and Jihlava massifs, were dated. Whereas the durbachite contains complex zircons and gives discordant U-Pb ages, the syenite contains rounded zircons, yielding concordant age of 335 Ma. Both rocks represent relics of the orogen-wide late Variscan magmatism, along with rocks from other parts of the Variscan belt in Europe. |
