earth's lower mantle

MgSiO_3 perovskite and ferropericlase (Mg,Fe)O are generally considered as the most dominant components in the Earth's lower mantle.

钙钛矿MgSiO_3和镁方铁矿(Mg，Fe)O作为地球下地幔含量最丰富的候选矿物，其高温高压实验数据用来与地震学探测数据进行对比以限定下地幔的真实矿物学组分。

The discovery of lower mantle mineral associations preserved in diamonds implies the possibility of “protokimberlitic magma” generation at 670km or deeper seat.

金刚石中含有下地幔矿物组合的包裹体，这一发现暗示，在６７０ｋｍ或更深处有“原金伯利岩浆”发生的可能性。

Like the core of earth, the mantle can also be divided into two concentric layers, the lower mantle and the upper mantle.

就像地球的核部一样。地幔也可分为两个同心圆圈层，下地幔和上地幔。

Like the earth, the moon is in layers, with a crust on the outside and a deep mantle below.

如同地球一样，月球上有地层，表面是一层地壳，其下是很深的地幔。

The middle and lower crust of upper mantle rising area is silpping towards the root of mountain around and is becoming thiner.

Therefore, the CMB is the beginning and the end of whole mantle convection.

因此,地幔底层既是全地幔对流的起点,又是全地幔对流的终点。

We do not know much yet about the moon's mantle, that section of superheated rock which goes down hundreds of miles below the crust.

我们对月球地幔所知不多，那些过热的岩石在外壳几百英里以下。

There one plate dives under the edge of another and is reincorporated into the mantle.

在这里，一块板块潜没到另一板块的边缘之下并结合人地幔之中。
