Abstract

Abstract

Based on regional compensation model and experimental isostasy,the isostatic response function of the Okinawa Trough was calculated by using gravity and topographic data.The results are shown as follows: the effective elastic thickness of the plate and compensation depth in the southern Ukinawa Trough is obviously greater than those in the middle Okinawa Trough.In reference with other geological and geophysical data,the deferences between the two portions are explained to be caused mainly by their differences in temperature of the lithosphere and the compensation mechanism.
