岩浆

The recent research shows that granitoids rocks within the ophiolites include not only the granites formed by fractionation of MORB at low pressure, but also the granites which formed by partial melting of gabbros of ophiolites in shear zone or intruded it during the formation and evolution of the ophiolite.

近年来的研究表明，蛇绿岩中的花岗质岩石不仅包括直接由大洋玄武质岩浆结晶分异形成的花岗质岩石，即传统意义上的大洋斜长花岗岩，还包括蛇绿岩在形成、演化过程中本身形成的和侵入的花岗质岩石。

The present crustal accretion model at a fast spreading ridge predicts at least an order of magnitude difference on average in the crystallization time, the time for a crystal to cool itself to a given temperature, between the upper gabbros and lower gabbros.

通过海洋地壳生成模型得到的典型快速扩张的太平洋中脊处海洋地壳内的热结构和速度场，推算出海洋地壳内的辉长岩层上、下组的成岩时间存在大于一个数量级的差异(成岩时间是指岩浆降温到某一指定温度时所经历的时间)。

The second phase quartz veins contain only twophase aqueous and single phase aqueous fluid inclusions; fluids came from meteoric water which interfused with magmatic water.

中期石英脉中主要发育气液两相包裹体和少量单液相包裹体，流体主要来源于大气降水，并且有少量岩浆热液混入。

He intruded himself into the conversation without a word of apology.

我们对入侵的岩浆和被侵入地层的性质做某些假定。

The side of the devastatedforest was even more barren than Tadorn Marsh.

岩浆的侵袭可以说是无孔不入。

Step-wise evaporation 207Pb-206Pb dating has been conducted for uni-genetic magmatic zircons from quartzofeldspathic gneiss and pegmatite, respectively, from Guandi complex, sporadically outcropped around Fangshan pluton in Zhoukoudian area, western Hills of Beijing.

北京西山周口店地区房山岩体周围关坻杂岩的长英片麻岩和伟晶岩脉具有类似简单岩浆结晶成因锆石的蒸发法Pb-Pb年龄。

During the early stage of Yanshan Movement in the Mesozoic Era, when the North China Plate had completed joining the Yangtze Plate to become a new united Craton massif, the tectonic movement turned to intracontinental orogenic stage, resulting in widespread magmatic activity and migmatization so that Tianzhu granitic batholith intruded the area on a large scale to form an embryo of the granite peak forest in the Tianzhu mountain area and ultrahigh pressure metamorphic zone further retraced its way, and consequently outcropped on the crust surface.

中生代燕山早期，华北、扬子板块已完成对接拼合，形成了新的统一的克拉通地块，构造运动已转入陆内造山阶段，引起广泛的岩浆作用和混合岩化作用，天柱山花岗质岩基大规模侵入，形成了区内天柱山花岗岩峰林胚胎，并导致超高压变质带进一步折返，并最终出露地表。

Partial melting of carbonated eclogites plays an important role in arc magmatism and volcanic outgassing.

碳酸盐化榴辉岩的部分熔融形成的熔体和气体对于弧岩浆的生成、CO2去气都有非常重要的作用，从而对整个碳循环研究具有重要的意义。

The mendous thick ore body was formed by sea floor volcanic eruptive sedimentation during the Devonian Period; the stringer ore body by Yanshanian magmatic hydrothermal fluid filling and overprinting. The reduction of old terrigenous detritus and some organic materials has important effect on the late ore fluids.

其中层状矿体为泥盆纪海底火山喷发沉积作用所致，脉状矿体可能来自燕山期岩浆热液充填迭加形成，古大陆碎屑物质和部分有机质的还原对后期成矿流体具有较大的影响作用。

Pb-Sr-Nd isotope tracing shows that the source of magma in the island-arc belt of Zhongdian area belongs to crust-mantle mixed type. The proportion of mantle material is 59.5% crust's is 40.5%. Similarly, for the Cenozoic alkaline-enriched porphyries, the source of magma is crust-mantle mixed type, but the proportion of mantle material is increased to 54.3%.

通过Pb-Sr-Nd同位素示踪，发现中甸地区岛弧带岩浆物质来源为壳幔混合型，印支期的地幔物质的比例m平均值为59.5％，地壳物质的为40.5％；剑川、北衙等地的新生代富碱斑岩的m值平均54.3％，也表现为壳幔混合型，但与印支期火山-侵入杂岩相比，其地壳物质的比例增高。
