地幔羽

地幔羽应称为氢羽。

The mantle plume is really the hydrogen plume .

看来，中国东部岩石圈变薄并不是深部地幔羽或大陆伸展作用的结果。

It seems that the lithospheric thinning of eastern China is not the result of the influence of the deep mantle plume or continental extension .

当板块移动时，一般假定地幔羽保持相对固定的位置。

It is generally assumed that plumes maintain a relatively constant position as the plates move .

尽管人们对有些较小的地幔羽可能有些疑问，但还是发现了数百个地慢羽。

Several hundred plumes have been identified , although some of the smaller ones may be questionable .

一些能量强大的地幔羽可以在地球表面产生一系列显著的，甚至是壮观的场面。

Some are energetic enough to produce conspicuous , even spectacular , displays on the Earth 's surface .

将热能转换成板块运动最普遍被引用的机制，是地幔羽的活动。

The most commonly cited mechanism for transforming thermal energy into the movement of plates is the action of plumes .

全球地震成象和深源地震资料表明，某些破碎的早期俯冲板片可能连续或间断性地下沉到核-幔边界处，井返回到起源于该边界层的地幔羽中。

Global seismic imaging and deep source seismic data have revealed that some formerly subducted fragments ( slabs ) seem to have continuously or intermittently sunk to the CMB and returned into the mantle plumes originated from the boundary .

深部流体的研究将对地幔柱（羽）的活动、幔源岩浆的形成、全球动力学过程及成矿作用作出贡献。

The study on deep fluids will contribute to the understanding of plume activity , generation of mantle magma , the global geodynamic processes and metallogenesis .
