Seafloor hydrothermal activity under the trench arc basin system, which is related to various problems, is an important research topic for the marine geology community. DSDP/ODP have supported drilling in the Mariana Trough of the Northwest Pacific trench arc hasin system and the Lau Basin of the Tonga Fiji Basin. The problems relating to the hydrothermal activity, tectonic attribution type of crust and active epoch of them have been studied, but no drilling has been done in the Okinawa Trough as yet. To meet the ODP vessel coming to the west Pacific during 1998, a proposal for ODP drilling in the Okinawa Trough is offered. 4 to 5 sites would be selected for drilling the 1300～1550m deep sea area ranging from latitude 27°15′～27°35′N and longitude 126°56′～127°10′E. The objectives are the solution of the following problems: 1. The maxinium penetration depth of the modern seafloor hydrothermal activity channel in the rock layers of the Okinawa Trough and the lithologic character of the hydrothermal fluid. 2. The type of hydrothermal fluid, lithogenesis and mineralization in the Okinawa Trough. 3. Hydrothermal activity and crust attribution. 4. Significance of studying hydrothermal activity in the evolution of trench arc basin system.
