The Initial Stage of Early Carboniferous Rifting in the Southern Urals: First The results of U-Pb Dating of Zircons from Granitoids of the Neplyuevka Complex

Popis výsledku v původním jazyce

Zircons from the Early Carboniferous granitoids of the Neplyuevka pluton of the Southern Urals have been dated (SIMS). Two age groups are distinguished among the studied zircons: group 1 from 334 to 342 Ma and group 2 from 354 to 356 Ma. The older ages probably correspond to the time of zircon crystallization from the melt, while the younger ones resulted from a partial loss of radiogenic lead by zircons during the cooling of the pluton or from the thermal impact of the Early Carboniferous or even the Early Permian intrusions. The formation of the Neplyuevka complex at the very beginning of the Carboniferous marks the most important stage in the geodynamic evolution of the Southern Urals, a rapid transition from island arc margmatism, which continued during the Devonian, to rift-related magmatism, which ended only in the Middle Visean.
