查询词典 basaltic

For a wide variety of lithologies from granite through gneiss, carbonate and amphibolite to basaltic rocks, it is shown that this relation is valid in the range 0～350 API and 0.03～7μW/m3 respectively with an error lower than 10%.

从片麻岩、碳酸盐岩、角闪岩、花岗岩到玄武岩，在这样宽的岩性变化范围内，显示出这种线性关系在0～350 API和0.03～7 μW/m3范围是有效的，其误差均小于10％。

The fluid-absent melting experiments of amphibolite do not support the assumption that, the intermediate "C-type" adakite (with SiO2 contents of 56 ~ 67 %) is originated from the melting of basaltic source-rock.

目前的实验岩石学结果不支持玄武质源岩部分熔融形成SiO2含量中等（56 ~ 67 %）的"C型埃达克岩"的假设。

Belonging to basaltic andesite, the pillow lava could be petrologically and geochemically compared with the underlying volcanic rocks.

它们的岩石学、地球化学特征完全可以和下伏火山岩对比，岩性属玄武安山岩。

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。

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。

After paying attention to his posting, I think he has brought back at least ONE basaltic lava rock.

在仔细看过他的发文后，我想他至少带回来了一个玄武岩熔岩。

All indications are that it is everywhere basaltic and relatively constant in composition.

所有的迹象只表明海洋地壳处都是玄武岩质的，组成也比较稳定。

It consisted of a brooding heap of black basaltic lave from the Tower of London.

它包括一个沉思一堆黑色玄武岩澡从伦敦塔。

With regard to the basaltic lavas, the felsic rocks resulted from partial melting of continental crust, which closely related to basaltic underplating.

古亚洲洋俯冲板块对古老岩石圈的交代作用在岩石圈减薄和置换过程中起了很重要的作用。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
