Isotopic timing of the magmatic and metamorphic events at the turn of the Archean and Proterozoic within the Belomorian belt, Fenno-Scandinavian shield
It is proved that dating high-grade metamorphism events through dating of migmatites is quite efficient. Our investigation has made it possible to identify two events of 2500 and 2700 Ma and to estimate the ag...

Age of granitoids in the Pripechora fault zone of the basement of Pechora Basin: First U–Pb (SIMS) data
Upper Precambrian basement of the Pechora Basin that is located between the Urals and Timan and is a part of the Pechora plate lies beneath 1–7 km of Ordovician-Cenozoic sediment cover. On the base of geophysi...

The U-Pb SIMS zircon age and geodynamic conditions of formation of granitoides of the Verkhisetsk batholith, the eastern slope of the Middle Urals
The U-Pb SIMS age dating of zircons from different-age granitoid assemblages varying in composition of the Verkhisetsk batholith shows that it comprises rocks of three age groups, formed at different stages of...

Paleoproterozoic A- and S-granites in the eastern Voronezh Crystalline Massif: Geochronology, petrogenesis, and tectonic setting of origin
The eastern part of the Voronezh Crystalline Massif hosts coeval S- and A-granitoids. The biotite-muscovite S-granites contain elevated concentrations of Si, Al, and alkalis (with K predominance) and relativel...

U-Pb age of autochthonous paleoproterozoic charnockite in the Aldan Shield
Autochthonous and parautochthonous charnockites in granulite facies of the Aldan Shield (the Aldan River upper flow) were dated. According to the geological observation data, the autochthonous and parautochtho...

New data on the age of ultrametamorphic granitoids of the Aldan granulite area (Eastern Siberia), consequences of metamorphic processes and possibilities of regional correlations of geological events
This work presents new U-Pb data (SHRIMP-II) for zircons from products of granitization and leucosomes of migmatites from amphibolite- and granulite-facies zones developed on rocks of the tonalite-trondhjemite...
