Zircon morphology and isotope U-Pb and Sm-Nd dating the rocks of the Kanozero alkaline granite massif (the Kola region)
The U-Pb dating zircon and Sm-Nd dating the whole rock and secondary minerals from the Kanozero massif of alkaline granites of the Kola region (the Fennoscandian shield) have been carried out. The age of alkaline granites of the Kanozero massif by zircon is 2667 ± 36 Ma, aplite-like alkaline granite...
