Melts and fluids evolution in the process of crust and mantle formation in Paleo-Proterozoic (2,2—1,75 Ga ago). Stratigraphy and magnetic activity

Геофизический журнал, 2017
Stratigraphy of metamorphic Precambrian complexes related to Paleo-Proterozoic is controversial. An additional sign permitting to correlate strata may be their material composition because in the Precambrian composition of deep fluids changed regularly.
