New geochronological constraints on the Ordovician plutonism and Cenerian orogeny in the Ötztal Complex, Eastern AlpsNARA Subscribed
This study presents new U–Pb–Hf isotopic data and zircon ages from the Ediacaran to Ordovician Ötztal Complex of the Eastern Alps in Austria to provide new constraints on the evolution of the northern Gondwana active margin in the “proto-Alpine” realm. The multistage tectonic evolution of the complex started with siliciclastic deposition presumably in an accretionary wedge that may have lasted from ca. 600 Ma to ca. 517 Ma. Th...
