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.
在此基礎上提出；本區鈣堿性巖漿巖系由地慢巖漿與1600百萬年前固結的大陸地殼混熔作用形成的巖漿産物。
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.
對這些鑛物進行了較詳細的化學成分分析，橄欖石、斜方煇石的化學成分顯示，二煇橄欖巖爲較弱虧損的地幔巖；
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.
鎂鉄質火成巖作爲分佈最爲廣泛的典型幔源巖石，已成爲探索地幔化學性狀及示蹤巖石圈深部過程的主要研究對象。
