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 pided 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。
