Early Paleozoic geodynamic evolution of the Eastern Central Asian Orogenic Belt: Insights from granitoids in the Xing’an and Songnen blocks
Geoscience Frontiers(2020)
摘要
The early Paleozoic tectonic framework and evolutionary history of the eastern Central Asian Orogenic Belt (CAOB) is poorly understood. Here we present zircon U–Pb geochronology, whole rock geochemistry, and Sr-Nd-Hf isotope data of the early Paleozoic granitoids in eastern CAOB to investigate the petrogenesis and geodynamic implications.
