mantle-derived rock

基本解释

On this basis, the paper points out that the calc-alkaline magmatic rock is the product formed by contamination of mantle derived magma with continental crust consolidated 1600m.
在此基础上提出；本区钙碱性岩浆岩系由地慢岩浆与1600百万年前固结的大陆地壳混熔作用形成的岩浆产物。
We have the chemical composition analyses in detail of these minerals. The chemical compositions of olivine and enstentite show that the lherzolite is a weak loss mantle-derived rock.
对这些矿物进行了较详细的化学成分分析，橄榄石、斜方辉石的化学成分显示，二辉橄榄岩为较弱亏损的地幔岩；
Mafic igneous rock, a widely distributed and typical mantle-derived rock, has become a major research source for revealing possible mechanisms for the chemical evolution of the mantle.
镁铁质火成岩作为分布最为广泛的典型幔源岩石，已成为探索地幔化学性状及示踪岩石圈深部过程的主要研究对象。
