岩浆

Early Proterozoic magmatic activity is one important part of Precambrin crustal evolution of the studied area.

早元古代岩浆活动是研究区地壳演化的重要组成部分。

The above new data give the information of the possible existence of Proterozoic basement in this district, and Yanshanian magmatism is of great significance for mineralization in the district.

以上这些新资料说明该区可能存在元古代基底的信息，且燕山期岩浆活动对本区成矿具有重要意义。

According to Gerard Kuiper, of the University of Chicago, the escape of gases from the moon's magma may have given the satellite a light, porous consistency, like that of a pumice stone.

芝加哥大学的Gerard Kuiper则提出，可能是月亮上岩浆气体的逃逸赋予了这颗星球轻飘多孔的硬度，就好象浮石那样。

It is suggested that the pyroxenite xenoliths were formed by the crystallization differentiation of the differentiated mantle-derived magma.

伊通新生代玄武岩中存在3种不同成因的捕虏体，其中上地幔岩浆分异结晶形成的辉石岩捕虏体中尖晶石具有独特的成分分带。

The crystalloblastic and cumulatic textures of pyroxenite inclusions imply that two magmatic underplatings could happen in the upper mantle.

变晶与堆积两种结构类型代表了两次岩浆底侵事件的发生。

This paper reports the investigation on the petrology of spinel harzburgite and olivine pyroxenite in the Darbut ophiolitic mélange, as well as the worm-like intergrowth texture composed of Cr-spinel and orthopyroxene wide-spreading in harzburgite. Our study shows that the observed intergrowth texture is not a graphic texture or a symplectite as assumed by previous research, instead, it is a product of the evolution of the Cr-rich magma formed after the melting of the primitive mantle.

通过研究西准噶尔达拉布特蛇绿混杂岩中方辉橄榄岩和橄榄辉石岩的岩石学特征，分析方辉橄榄岩广泛发育的铬尖晶石和斜方辉石构成的蠕虫状共生连晶结构的成因，得出结论认为：这种共生连晶结构不是前人所认为的文象结构或者石榴石的后成合晶，而是原始地幔岩熔融形成富铬岩浆的演化产物。

The olivine-pyroxenite and pyroxenite with crystalloblastic texture and cumulate texture in Mesozoic igneous rocks from western Shandong and western Liaoning reveal that the several magmatic underplating events had taken place before the formation of Mesozoic host-rocks.

鲁西、辽西中生代火成岩中具有变晶结构和堆积结构的橄辉岩-辉石岩类包体的岩石学、矿物学、元素和同位素地球化学研究揭示了该区中生代寄主岩形成之前，曾有过多次的岩浆底侵作用发生。

Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

本论文以该地区晚中生代中–基性岩墙群为主要对象，研究了它们的岩石学、地球化学及同位素年代学等，对岩浆源区的性质、构造环境、成因等进行了讨论，获得以下重要认识： 1、福建沿海地区晚中生代中–基性岩墙成群产出，侵入到晚中生代花岗岩及火山岩中，岩性有辉绿岩、角闪辉绿岩和石英闪长岩等，以辉绿岩类为主，产状较陡，北东、近东西及北北东走向，大多未发生变质或变形，保持了岩墙形成时的应力状态。

The temperature of basin was influenced greatly by matle heat conduction, magmatic heat and radioelement decay during the time of Early Permian-Late Permian rifting, while in the down-warped basin from the late stage of Late Permian to the present the temperature has been greatly affected by geothermal gradient and tectogenetic transition heat.

认为早二叠世-晚二叠世早期裂谷作用阶段盆地温度主要受地幔热传导、岩浆体热和放射性元素衰变的影响，晚二叠世晚期至今坳陷盆地阶段主要受地热增温率和构造运动转化热的影响。

When O and radiogenic isotopic measurements are employed as tracers to evaluate magma-country rock interaction it is essential to provide evidence that open system processes have not perturbed the isotopic systematics.

用氧同位素和放射性同位素示踪岩浆和围岩相互作用时，必须在开放体系没有扰动同位素系统情况下进行。
