查询词典 magmas

Sr-Nd-O isotopic element system research proves that granitoids magmas form in open system and compose a large amount of mantle contents.

Sr-Nd-O同位素系统研究表明花岗岩浆是在开放系统环境下形成的，其中含有大量地幔组分。

The most fluid magmas erupt quietly and flow from the vent to form gently sloping shield volcanoes.

熔岩大部分以液态形式静静的爆发，从开口处流出，会形成坡度较缓的盾形火山。

All these characteristics, largely relevant to the nature of the plume-generated magma source and/or parental magmas, and magmatic evolution, can be used to identify similar rock types in natural occurrence.

这些特点与岩浆源区或母岩浆的性质以及岩浆演化条件有关，为自然界同类岩石的甄别提供了依据。

The mixing of the mother magmas and the crustal matters released Cu, Au-bearing epithermal. These ore metal-bearing epithermal ultimately formed ore deposits in the Tongling region.

我们认为，俯冲作用导致板片洋壳部分释放的超临界流体，受其影响地幔楔熔融形成富集S等挥发份和Cu、Au等成矿元素的母岩浆，为铜陵地区提供了成矿物质来源，其与地壳物质的混合释放出含Cu，Au的热液，最终形成铜陵地区目前矿床分布格局

On the other hand, the low-Ti/Y type picrites and low-Ti basalts were also probably derived from the same plume source, but magmas of the low-Ti/Y type picrites most likely experienced a mixture with more than 15% bulk SCLM material; and magams of the low-Ti basalts were probably contaminated with over 15% melt from SCLM.

木里低Ti／Y型苦橄岩具有低的γOs(-4.1～-0.2)和高εNd_(t(+3.2～+6.6)，它们也未受到地壳的混染，Nd-Os同位素二元混合模型表明它们可能是由地幔柱起源的苦橄质原始岩浆混合了15％或更多的SCLM物质形成的；与其共生的低钛玄武岩具有低的γOs(＜0)和低的εNd_(t值，它们可能是由地幔柱起源的玄武质原始岩浆混合了15％或更多的SCLM的熔融物质形成的。

Some characteristic ratios suggest the picrites and ankaramites were derived from asthenospheric mantle, and high Os/Ir ratios reflect the involvements of pelagic sediments. Pd/Ir versus Ni/Cu diagram implies that the picrites and ankaramites were not primary magmas, but MgO-high basalts with excess olivines, whereas Pd versus Cu diagram suggests a S-undersaturated primary magma.

一些铂族元素的特征比值指示了苦橄岩和富辉玄武岩起源于软流圈地幔，而高的w/w比值则暗示了源区中有深海沉积物的加入。w/w-w/w图解说明本区的苦橄岩不是原始岩浆，而是原始的高镁玄武岩中有过剩橄榄石的加入，而w-w图解则说明原始岩浆硫不饱和。

The results show that the temperatures of metamorphic dehydration for these pelites have a closely negative linear correlation with the corresponding pressures, which provides further experimental evidence for the depth at which magmas in subduction zones originate.

在高温高压设备上完成了多种天然含水泥质岩的高压差热实验，成功地获得了泥质岩发生高压变质脱水作用的温度与压力呈线性负相关的关系，为俯冲带岩浆起源的深度提供了进一步的实验证据。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
