| 摘 要： | 简述了冲绳海槽火山岩的研究意义、研究历史、现状及存在问题，提出了今后深入研究的思路与展望，指出应基于现代地球化学理论和方法，从板块构造沟弧盆体系岩浆作用的角度，将冲绳海槽这一典型幼年期弧后盆地中复杂多变的火山岩作整合型归纳和思考，既揭示不同岩石系列的成因联系，又注重将岩浆作用与构造环境相结合，并在与成熟弧后盆地火山岩的对比中揭示弧后盆地早期扩张过程中岩浆作用的特性、规律与标志，以揭示弧后盆地早期扩张的构造动力学过程。

| Abstract: | The research significance and history,situations and problems concerned as well as development and prospecting of further deep study on volcanic rocks from Okinawa Trough,have been briefly expounded in this paper.It is emphasized that,for the different kinds of volcanic rocks in Okinawa Trough,typical active back arc basin in the initial stage of spreading,the study should be based on the modern theory and technique of geochemistry and also on the integrated induction and thinking in view of magmatism in arc trench system.Futhermore,our study should also pay attention to either the genetic link among the different series of rocks,or the link between magmatism and tectonic environment.The characters,regularity and sign of magmatism during the initial spreading of back arc basin should be revealed through comparing with the volcanic rocks from mature back arc basin,so as to make clear dynamic process during the initial spreading stage of the back arc basin. |
