Abstract

The fact that gneissose granites and gabbros of the Nyatygran Complex in the Bureya Continental Massif are not Palaeoproterozoic in age, as previously thought, but Neoproterozoic, ~933 Ma is proved. New data with the first direct evidence of Early Neoproterozoic magmatism in continental massifs composing the Bureya–Jiamusi Superterrane are given. At the moment, the obtained age estimates are the oldest for the magmatic rocks of this superterrane.
