primary magma meaning in English
原生岩浆
原始浆岩
原始岩浆
Examples
- During the magma evol ution , this primary magma suffered effects of the containing water fluid and a small extent contaminate of continental crust . according to all of features above , the paper analyzes the formatting mechanism of high - mg volcanic rocks
岩浆演化过程中遭受到了含水流体的影响及轻微的陆壳混染。根据以上特征对高镁火山岩的形成机制作了分析。 - Two ree distributed pattern , lree - depleted and flat , which display a specific character of typical mid - ocean ridge tholeiite , indicate that primary magma may be derived from near primary or a typical large ion lithophile element ( lile ) - depleted mantle
岩石稀土元素配分模式可分为lree平坦型和lree亏损型两类，指示了其原始岩浆起源于近原始或典型的大离子元素亏损型的地幔，为典型的大洋中脊拉斑玄武岩的特征。 - Such features can be ascribed to lower degrees of partial melting and greater melting depths . in particular , the decoupling between the lowest nag and highest tig tends to indicate residual jadeite during melting process so that na behaved as a moderately compatible element to lower the naao concentration in these rocks . this is consistent with the ree patterns in the high - ti diabases that have the highest ( gd / yb ) cn ratios than other two groups , which suggest a more important role of residual garnet in generation of the primary magmas
运用mgo = 8进行标准化，结合岩石成因理论讨论了三大系列辉绿岩的形成相对深度和熔融比例，其中高ti系列的原始岩浆形成深度大，熔融比例小，源区相对最为富集易熔组分；低ti系列的熔融深度最浅，比例最大，源区相对亏损易熔组分；过渡ti系列则介于前两大系列之间。 - On the basis of the study on the petrology , trace element , and isotopic geochemistry , the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting . one is the basanite - alkaline basalt - olivine tholeiite magma series , which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma , which are generated by partial melting of the garnet iherzolite
岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。
