查询词典 magmas

Petrological and geochemical characteristics of alkali-rich porphyries suggest that magmas might not be generated from subducted oceanic slab, but likely from the base of thickened crust, corresponding to eclogite-facies.

富碱斑岩产出的地质背景及岩石学和地球化学特征表明，富碱斑岩并非起源于俯冲的大洋板片，而是源于加厚地壳的底部，源区为榴辉岩相岩石。

And then a local extension took place in the region of intra-Eastern Tethys when the India plate drifted to the north but suffered the resistance from the Lhasa block, contemporarily, the intra-oceanic subduction are triggered, subsequently, magmas derived from a partial melting of mantle wedge which suffered from the modification by subducted continental marginal clastics and oceanic sediments upwelled along the oceanic ridges, forming several small marginal basins during 120～128 Ma, and thus lead to the so-called SSZ-type oceanic crust.

于120～128Ma，一些规模较小的边缘洋盆形成，卷入陆缘碎屑和洋壳沉积的地幔楔发生熔融产生岩浆，沿着破裂的扩张脊上涌产生了具有TNT负异常的SSZ型新洋壳，期间产生了俯冲洋壳重熔作用，标志着年轻的热的洋壳俯冲形成的埃达克岩侵入于仁布SSZ蛇绿岩地幔橄榄岩中。

Gold came from the mantle and/or from remelted crust, while large, deep-cut faults and passageways of the remelted magmas provided possibility of transportation of the hydrothermal fluids, and brittle, brittle-ductile overlapped faults developped at the moderate-shallow levels of the mantle plumes, and related decollements, provided ideal sites for the precipitation of hydrothermai fluids.

金主要来自地幔及重熔地壳，深大断裂及重熔岩浆通道为成矿热液的迁移提供了有利条件，中浅层次的幔枝隆起及外围滑脱带中的脆性、韧—脆性叠加断裂为矿液提供了沉淀场所。

The geochemical behavior of tungsten in magmas, hydrothermal fluids, supergenesis, and related effects on bionts, environment and health are also discussed.

Magmas in transit to the surface will further supplement this heat.

向地表运移的岩浆将进一步补充这种热量。

Low concentration of compatible elements in all the rocks indicates the magmas experienced different extent of differentiation crystallization.
