查询词典 mantle

The lithospheric mantle of the Chinese continent, as a whole, is in compressive tectonic regime. 2. The lithosphere of eastern portion of the Chinese continent, being in extensional regime for level-shallow and motion eastward but westward dipping imbricated subduction that formed by high- and lower velocity slabs within lithosphere, suggests that it is in compressional regime in deep levels as a whole.

Lherzolite depleted LREE is a relict of original mantle rocks at different degrees of partial melting;harzbugite with U-typed REE distribution patterns is a product of highly depleted pyrolite which has been metasomatized by melt ...

二辉橄榄岩亏损轻稀土，是原始地幔经不同程度部分熔融的残留体。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

Mafic dyke swarms are considered to be intrusives of mantle-derived magmas formed under an extensional setting.

基性岩墙群是地壳伸展背景下，来自地幔的基性岩浆侵入体。
