介绍了日本东北部俯冲带中水向地幔深部运移的地震学证据。资料表明,水在100km以上的浅部从含水的洋壳中释放出来,然后在俯冲板块顶部形成含水的地幔物质沟渠,这就是水进入地幔深部的通道。本文对寒冷的俯冲带环境中水从海洋运移到地幔深部的机制提供了直接证据。
The seismological evidence of the migration of subduction zone water in the northeastern Japan to the deep mantle is presented. The data show that water is released from the aquiferous oceanic crust over a depth of 100 km and then forms an aquifer of mantle material ditches at the top of the subducting plate. This is where water enters the deep mantle. This paper provides direct evidence of the mechanism by which water migrates from the ocean to the deep mantle in the cold subduction zone.
