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。

This implies a major stage of crustal growth in Proterozoic time and remelting of the crustal material in Early Jurassic time;(5) The Oligocene-Miocene adakites contain magmatic zircons that show similar Hf isotope compositions to the Cretaceous-Paleogene Gangdese batholiths, providing a key constraint that allows evaluation of the nature and timing of crustal thickening in southern Tibet owing to the India-Asia collision; and (6) As a whole, the Hf isotope information observed in zircons from the above Transhimalayan rocks demonstrates a temporal variation in εHf values, and thus TDMC ages, that suggests multiple stages of orogenic or crustal formation events.

五、渐新世、中新世的埃达克岩,其岩浆锆石的铪同位素特徵与白垩纪、古第三纪冈底斯岩浆相似,因而为藏南在印亚碰撞以后,地壳增厚的时间与机制提供了关键性的制约;六、综观上述藏南火成岩中的锆石,它们与时变化的铪同位素初始值及其对应的模式年龄记录了拉萨地块多阶段的造山与地壳形成历史。

Accompanying the Jungar plate subdueted dewnwards along the northwest edge of Siberian eraton, the volatile-rich felsie biotite diorite batholiths and a lot of fracture-controlled quartz diorite vein intruded the are-back basin, Au preferently distributed within the disseminated magmatic sulfide during granitoid melt crystallization

There is argument whether the fluids responsible for mineralization is a dominant magmatic source or controlled by host rocks. The main genetic models include "an evaporite source model","a fluid heating model" and "a magmatic-hydrothermal model".

对成矿流体是主要来自岩浆还是受围岩控制尚有争论,成矿模式有蒸发盐来源模式、外来流体加热模式和岩浆-热液流体模式。

SA — Magma Spit: The core hound may spit globs of magma as a ranged attack with a range increment of 20 feet (maximum range 100 feet).

SA —岩浆唾液:熔核猎犬可以吐出岩浆团作为射程加成为20尺的远程攻击(最大射程为100尺)。

The igneous diversity is not only induced by the magmatic processes but also by the processes caused production of magmas.

火成岩的多样性不仅仅取决于岩浆作用过程,而且也取决于岩浆形成过程。

Ni, Cu and PGE are very important in the study of origin and evolution of mantle derived magmas and the formation of the related magmatic sulfide deposits, because their geochemical natures are different from other trace elements.

Ni、Cu和PGE具有不同于其他微量元素的特殊的地球化学性质,这些特殊的性质使得它们在幔源岩浆起源和演化以及岩浆硫化物矿床的成因研究中具有不可替代的作用。

The flow of magnetons in the magma normally flows in the direction of the Earth's magnetic field, N up, S down, but what would occur in a pool of magma, trapped, under the direct influence of Planet X which is overhead near the position of the Sun.

岩浆里的磁子正常情况下是沿着地球磁场的方向流动的----在北极处上升,南极处下降,但对于一片直接受到行星 X 影响(行星 X 就在太阳附近,地球上方),并被困住的岩浆来说,会发生什么事情呢?

Volcanic rocks shaped by a volcanic movement tend to occur vugs and fissures as spaces for hydrocarbon storage during rapid magma condensation;the volcanic debris deposits are characterized by expanding and dispersing in water,being either favorable to packing pores,and becoming good sealing caps,or to preservation of oil/ga...

火山活动形成的火山岩,在岩浆迅速冷凝过程中会产生孔洞和缝隙,成为容留油气的空间;火山活动形成的火山灰沉积,具有遇水膨胀和分散的特点,地层孔隙被其它充填后而成为良好的封存盖层并能抗御新构造运动的破坏而有利于油气田的保存;火山活动提供1020~1200℃的岩浆和300~400℃的热液流体携带的热能,为油气运移提供热动力条件,促进油气运移;火山活动在沉积盆地内形成的火山岩体与侵入岩体,为含油气盆地增加了一种非构造圈闭———火山岩岩性圈闭。
