查询词典 magma

The δ^34S values of ore minerals vary slightly from -3.1‰ to +0.7‰ with an average value of -1.1‰ and the δ^34S values of the ore-bearing porphyries are -1.4‰ and -1.5‰, indicating that sulfur is mainly derived from the magma of porphyry.

雪鸡坪铜矿S，Pb同位素组成共同指示成矿物质主要来自于深部岩浆，这种岩浆可能主要起源于俯冲洋壳板片的部分熔融并受到少量地壳物质的混染。

The plate previously subduced had started to break off, which resulted in its crust materials and mantle materials being mixed up, and formed the source region of richening molten materials. The large-scale magma activity appeared in the two blocks of Himalayan and Lhas-Gangdese.

先行俯冲板片发生断离，其地壳物质与地幔物质混合，从而形成板内富集熔体的源区，并在喜马拉雅—拉萨块体内形成了大规模的岩浆活动。

When the magma cools and solidifies,volcanic rock. Reversals of the field give rise to a series of magnetic

岩浆冷却并凝固下来后，地磁场的方向和磁极被保留在磁化了的火山岩中。

During this period, the partial melting of young and hot subducted oceanic crust at 75-85km produced he adaktitic magma.

在这期间，年轻的热的洋壳俯冲至75-85km深度左右时发生部分熔融并形成埃达克岩浆。

Therefore, the fluid dehydrated from subducting slab should have been added to magma at its forming stage or play an important role in the melting of mantle.

俯冲板块脱失流体的混入可能发生在岩浆作用早期，或者说俯冲板块脱失流体对地幔熔融产生岩浆起了重要作用。

In about 25,000,000 year, the Changbai Mountain area experienced 4 volcanic eruption activity, the basaltic magma embarked from the upper mantle, upwelled unceasingly along the earth's crust in giant crevasse, spouted the surface by the huge energy (in geology to be called crevasse type volcanic eruption).

在大约2500万年的时间里，长白山地区经历了4次火山喷发活动，玄武岩浆从上地幔出发，沿着地壳中的巨大裂隙不断上涌，以巨大的能量喷出地表（地质学上称为裂隙式火山喷发）。

Magma upwelling within the Earth's shell towards her solid crust has been heating the oceans for some time now.

岩浆上涌的地球壳牌对她固体地壳已暖气海洋一段时间了。

Mechanically, the extensional structures were controlled by extension in direction of NE-SW and magma upwelling vertically.

在形成机制上主要受控于NE-SW向的伸展作用和垂向上的岩浆上涌作用。

Hot spot: a place in the upper mantle of the earth at which hot magma from the lower mantle upwells to melt through the crust usually in the interior of a tectonic plate to form volcanic features; also: a place in the crust overlying a hot spot.

另外，根据有些地质理论，hot spot 的位置一般是相对固定不变的，也就是板块可以漂移，但它却保持不动 54。

The evolution tendency of its magma suggests that the Wudalianchi rift belt is still in a course of continuing evolution without a sign of coming to an end.

进一步从岩浆演化的趋势认为五大连池裂谷带将持续演化而不会夭折。

I can not make it blossom and suits me

我不能让树为我开花
