【Abstract】 There are four modern seafloor hydrothermal activity area in the Middle Okinawa Trough. The hydrothermal activity of those area are different from each other,and also different from those in the MidOcean Ridge. What is the main control factor and how it influence the hydrothermal activity are unknown. ODP’s drilling in the Middle Okinawa Trough may be give the best explanation.更多还原
