    冲绳海槽地区地球物理场特征及地壳结构分析

    FEATURES OF GEOPHYSICAL FIELD AND CRUSTAL STRUCTURE OF OKINAWA TROUGH AND ITS ADJACENT REGIONS

    • 摘要: 利用冲绳海槽地区最新的调查资料,系统地总结和分析了冲绳海槽地区地震波场、重力场、磁力场、热流场的特征,通过居里面的反演和莫霍界面的计算,结合编绘的图件对该地区的居里面深度和莫霍面深度的分布特征进行了研究。居里面的深度为4~15 km,莫霍面深度在4~28 km之间,综合分析以往OBS的调查结果和地震资料解释成果,对该地区的深部地壳结构进行了探讨。

       

      Abstract: Based on the latest geophysical data from the areas of the Okinawa Trough, the paper analyzed the characteristics of the seismic wave field, gravity field, magnetic field and heat flow field of the Okinawa Trough, we computed the Curie depths and Moho depth of the Okinawa Trough, studied the distribution patterns of the Curie depth and the Moho depth. The Curie depth changes from 14 km to 28 km and the Moho depth changes between 4 to 28 km in the Trough and its adjacent. OBS survey and seismic data interpretation are adopted for revealing the deep crustal structure of the Trough and surrounding areas.
