Abstract
U–Pb (ID-TIMS) geochronological studies of garnet from aillikites of the Kandalaksha dyke swarm (Kola alkaline province) were carried out. The obtained estimate of the U–Pb age of the garnet (374 ± 3 MA) coincides with the interval (373–377 MA) of the main stage of alkaline magmatism of the Kola province (LIP). This allows us to conclude that the formation of rocks of the dike complex of the Kandalaksha Bay and rocks of the phoidolite series of alkaline-ultrabasic massifs of this province is synchronous.
