查询词典 magma

Geysers spout up where a column of underground water is heated to boiling by "magma," or molten rock.

从间歇泉的形成是由于一系列的水地下水被岩浆热过后形成水柱而喷发出地面。

Based on the study of mineral crystallization sequence, solidus temperature and growth rates of quartz and albite, it suggests that Li_F_Na enriched granitic residual magma is qualified for the f...

对矿物结晶顺序、石英和钠长石的生长速率以及固相线温度的研究表明，富锂、氟、钠的花岗质残余岩浆完全具备形成雪球结构的条件。

So it may be inferred that the protolith of the amphibolite is the product of different degrees of partial melting of the mantle in a magma arc.

显示出壳源性质或者是受到大陆下地壳的混染作用而形成。

Peraluminous grarfites in Tibet occurred in a stage of collision between two continental crustal plates and the magma originated from anatexis of the upper crust.

喜马拉雅过铝花岗岩是陆内俯冲的岩石学记录，而冈底斯带过铝花岗岩更可能是特提斯洋壳北向俯冲的岩石学响应。

On the other hand, what we stated in the text book is not wrong. We only want to express that not all the subduction magmatism generate andesite. Many intra-oceanic island arcs are dominated by basaltic rocks. We did not explain why because that would involve many high-level concepts like magma fractionation.

而我们在课本中的叙述也没有错，我们只是想提醒并非所有隐没作用都会产生安山岩岩浆，许多大洋中的岛弧都是以玄武岩浆为主，像是东加与马里亚纳。

Working from outside the basin in to the Mare Basalts, they find the surface composition changes from Feldspathic breccias (Feldspar is a rock that crystallizes from magma) to shocked Anorthosite (a type of feldspar that makes up the light areas of the moon), to unshocked crystalline anorthosite, to high Calcium pyroxene (a rock made of silicate minerals) and pyroclastic rocks in the center.

研究发现：从盆地外边到盆地内部的玄武岩海（盆地内部的熔岩形成的地质结构），月球表面的地质结构依次是：长石质的角砾岩（长石是火山熔岩结晶形成的岩石）、经过冲击的粒状火成岩（构成月球阳面的一种长石）、没有经过冲击的粒状火成岩结晶体、高钙辉石（一种由硅酸盐构成的岩石），最中心的位置是分裂状的火山岩石。

The crust became the white anorthosite, which floated atop the magma to form the lunar highlands. The basalt erupted later and subsequently solidified in the lowland marea.

这个壳后来变成白色的斜长岩，它漂在岩浆上面形成月球的高地，后来，玄武岩的岩浆喷发并且凝固在低地区域。

This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

根据这一年代资料，结合对月岩样品进行的短半衰期Hf-W与Sm-Nd同位素体系的研究结果，认为月球大致形成于45亿年，其后开始由岩浆海导致的内部核－幔－壳的分异，岩浆结晶的低密度斜长岩构成最初的月壳，而密度大的岩石构成月幔，而此月幔则成为后来月海玄武岩的主要岩浆源区。

According to the characteristics of element distribution, the spinel compositional zonings were formed by the chemical equilibrium between the crystals and magma during magma crystallization, not by ion diffusion in the processes of subsolidus equilibrium.

从尖晶石成分分带的元素分布特征判断，其形成不是固溶体相平衡过程中的离子扩散，而可能是化学平衡过程中结晶矿物与熔浆之间化学成分平衡的结果，属于化学平衡导致的成分分带。

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。
