Lu–Hf isotopic systematics of zircon from lower crustal xenoliths in the Belomorian mobile belt
The structure, geochemistry, and U–Pb and Lu–Hf isotopic composition of zircon crystals from garnet granulite xenoliths of the lower crust in the Belomorian mobile belt have been studied. It has been established that Early Paleoproterozoic zircon, 2.47 Ga in age, is primary magmatic and formed durin...
