The Oldest Grey Gneisses and Tonalite-Trondhjemite Granodiorites in the Fennoscandian Shield: ID-TIMS and SHRIMP Data
《Open Journal of Geology》2020年第2期124-136,共13页Tamara Bayanova Evgeniy Kunakkuzin Pavel Serov Ekaterina Steshenko Elena Borisenko Alexander Larionov Olga Turkina 
Genesis of the oldest continental crust retains a marked trace in the Earth’s evolution over its 4.5 Ga history. Despite ample isotope data on the role of the continental crust in the Earth’s evolution, there has be...
