查询词典 xenocrysts

The helium isotope results of nodules in C-CZone, eclogite in Dabie-Sulu region and mantle xenoliths and xenocrysts in Cenozoic basalt ineastern China were reported in this thesis.

本文重点介绍了C-C区海底多金属结核、大别山榴辉岩和中国东部新生代玄武岩中幔源包体的氦同位素研究成果。

The Cenozoic lithospheric mantle beneath the western Qinling was refractory in major element compositions based on the mineral compositions of xenoliths and xenocrysts and experienced complicated deep processes.

地幔捕虏体和捕虏晶的地球化学特征表明西秦岭新生代岩石圈地幔具有难熔的特征，并经历了复杂的深部过程。

All of the above characteristics as well as poorcrystallized, abundant peridotite inclusions, few xenocrysts, and elements covariation trend indicate that the Tianheyong basalts were solidified from primitive basaltic magma.

上述所有特征以及岩石结晶程度低、富含橄榄岩包体和少量捕虏晶、元素变异关系等均表明，天和永玄武岩是原生玄武岩质岩浆固结的产物。

The variations of helium isotopic ratios can be observed in these xenoliths andxenocrysts from different area, or even from same area, indicating that the xenocrysts didntdirectly crystallize from basaltic magma, and basaltic magma is not directly related to thesemantle lherzolites xenoliths.

提出幔源包体和高压巨晶的氦同位素组成均反映了其地幔源区的特征，与寄主玄武岩无必然成因联系。

橄榄石捕虏晶具有清晰的环带结构。

The mantlelherzolites xenoliths with lower ~3He/~4He ratios may be from upper metasomatic enriched mantleand the garnet xenocrysts may be from below extra-depleted mantle formed by metasomatism.

具有异常低~3He／~4He比值的幔源包体可能来自上部交代富集型地幔源区；具有较高~3He／~4He比值的高压巨晶可能来自下部极度亏损地幔源区。

Olivine xenocrysts have clearly-zoned textures.

根据橄榄岩的化学成分特征可以将其分为两类：H 型橄榄岩和 L 型橄榄岩。
