| 摘 要： | The following geochemical types of granitoids have been investigated in the Mongol-Okhotsk belt:tholetitic,palingenic calc-alkaline,latitic,plumasitic and arpaitic rare-metal granites.Plagiogranites of the tholeiitic series occur within the Mongol-Okhotsk suture,indicating a subduction environment.The calc-alkaline granitoids responsible for the batholith-like intrusions and their formation are related to collision environments.The latest granitoids of the latite series and rare-metal granites came into existence after the collision of continental masses,providing evidence of intraplate magmatism.

| Abstract: | The following geochemical types of granitoids have been investigated in the Mongol-Okhotsk belt: tholeiitic, palingenic calc-alkaline, latitic, plumasitic and agpaitic rare-metal granites. Plagiogranites of the tholeiitic series occur within the Mongol-Okhotsk suture, indicating a subduction environment. The calc-alkaline granitoids responsible for the batholith-like intrusions and their formation are related to collision environments. The latest granitoids of the latite series and rare-metal granites came into existence after the collision of continental masses, providing evidence of intraplate magmatism. |
