U–Pb (ID-TIMS) Age of Garnet from Aillikites of the Kola Alkali Province.

The U–Pb (ID-TIMS) geochronological studies of garnet from aillikites of the Kandalaksha dike swarm (Kola alkali province) were carried out. The estimated U–Pb age of garnet (374 ± 3 Ma) coincides with the major stage (373–377 Ma) of alkali magmatism in the Kola Province (LIP). Hence, it can be concluded that rocks of the dike complex of Kandalaksha Bay and foidolite-range rocks of alkali–ultrabasic massifs of this province were formed synchronously. [ABSTRACT FROM AUTHOR]
