Based on the complexity of the sources for the sediments in the Okinawa Trough, the sequential extraction procedure was applied to the hydrothermal influenced sediments in the core H9 recovered from the middle Okinawa Trough. Five fractions, including exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter, and residual were acquired. Based on detailed analysis for major, minor and rare earth element compositions, the distributions of the elements in various speciations of the sediments were determined and the controlling mechanism was discussed. The variations of hydrothermal signatures in the core, partitioned from the terrigenous, volcanic and biogenic materials, have been demonstrated and the accumulation rates of some elements were evaluated.
