| 英文摘要 | In general, the arc magmas are oxidized, forming magnetite-series granitoids. However, there are also ilmeniteseries granitoids at convergent margins. The mechanism that controls the formation of different types of granitoids remains obscure. Here we show that the temporal distributions of ilmenite-series granitoids in Japan have a good correlation with oceanic anoxic events (OAEs). The subduction of OAE sediments with high contents of organic matters releases reducing fluids/melts into the mantle wedge, leading to the formation of ilmenite-series granitoids. This is supported by sulfur isotope compositions and high concentrations of organic gas of the ilmenite-series granitoids in Japan. The temporal correlation between OAEs and Il-series granitoids suggests that the OAE sediments was predominantly distributed within short distances (<2000 km) along the coast. Considerable amount of organic matters are recycled back to the surface during plate subduction, and thus have major influences on carbon recycling, and climate changes, as well as oxygen fugacity of convergent margin magmas and associated mineralizations. |
