... that they were initially enriched in granitophile (including ore-forming) trace elements. This suggests consanguinity between the intrusions of the Shakhtama complex (J 2 –J 3 ) and the ore-bearing Kukul’bei rare-metal complex of granites and leucogranites (J 3 ) (Aga zone, Transbaikalia). Since granitophile...
