Mineralogical and geochemical analysis reveals Meso–Neoproterozoic granitoid origins in Siberia, indicating early Grenvillian orogeny.
Mineralogical–petrological, geochemical, and isotope geochronological studies provide new data on the major- and trace-element composition, petrogenesis, U–Pb zircon age , and Sr and 147Sm–143Nd isotopic parameters of the granitoids of the Ryazanovsky massif near the Yenisei fault zone of the Yenisei Ridge. The origin of these rocks at the Meso–Neoproterozoic boundary (1013 ± 9.9 Ma) marks early Grenvillian orogeny in the western margin of the Siberian craton.
