"Fortunately, each hypothesis predicts a very different mantle composition," Strom says.
“幸运的是，每一个假想预测着不同的地幔组成，”斯特罗姆说。
Moreover, the Moon's composition, though similar to that of Earth's mantle, is not a precise match.
此外，月球的成分虽然与地球的地幔相似，但并不完全吻合。
Much more than the crust, the mantle contains information about a planet's or moon's total composition.
地幔包含的远远不仅是地壳，还有关于行星或卫星的总体构成的信息。
These, together with reasonable guesses about the Earth's overall composition, have been used to put together the familiar model of an iron core, a rocky mantle and a thin crust.
这些连同有关地球总体构成的合理猜想，一起形成了我们熟悉的地球模型——铁质地核，岩石地幔和较薄的地壳。
There have been large uncertainties in the formation history of Mars because of the unknown composition of its mantle, the rock layer that underlies the crust.
因为其地幔的未知混合物，火星形成历史上还有诸多不确定因素。
There have been large uncertainties in the formation history of Mars because of the unknown composition of its mantle, the rock layer that underlies the crust. Dauphas said.
因为其地幔的未知混合物，火星形成历史上还有诸多不确定因素。地幔是一个位于地壳下面的岩石层。道法斯说道。
It shows that the magma was derived from the upper mantle which was altered or affected by subduction composition, and the mantle source was of chemical inhomogeneity.
这表明岩浆起源于受俯冲组分改造或影响的上地幔，且地幔源区存在明显的化学不均一性。
This paper deals with the advance in study of the composition, geochemistry and deep seated fluids of lower mantle.
主要论述深部地幔的组成、地球化学及深部流体研究的进展。
The ratios of incompatible elements reflected that the magma source departed from the composition of primary mantle and had the characteristics of the enriched metasomatic mantle.
强不相容元素比值反映岩浆源区明显偏离原始地幔组分，具有富集型异常地幔岩浆源区特征。
Composition of carbon and oxygen isotope indicates that origin of carbon comes from mixture of the crust and mantle.
碳、氧同位素组成指示碳来源于壳幔混合。
And we need to find out, because much more than the crust, the mantle contains information about the planet's or moon's total composition.
