The influence of Ryukyu subduction on magma genesis in the Northern Taiwan Volcanic Zone and Middle Okinawa Trough - Evidence from boron isotopes

The δ11B data also provide insight into the nature of the different subduction components. A three-end-member mixing model suggests that MOT and NTVZ magmas may have incorporated subduction fluids derived from altered oceanic crust or serpentinite, whereas the onshore volcanoes in the NTVZ, and in particular in the Tsaolingshan, may have involved a higher proportion of sediment component.
