花岗岩

The large volume of garnet granite is possibly direct products of anatexis of the Khondalite series, which is indicated by their feldspar Pb composition consistence and some petrological evidences.

花岗岩中长石Pb同位素组成显示，石榴石花岗岩是孔兹岩系部分熔融的直接产物，而淡色花岗岩不是孔兹岩系简单的部分熔融产物。

The volcanic rocks of the Xiong'er Group is also widespread in the Baoji and Lvliang area and also appear as 1.75Ga-old mafic dyke swarms, A-type granites, later anorthosite and rapakivi granites (1.75-1.70Ga), and alkaline granitoids (~1.65Ga). These intrusive rocks are assumed to have genetic link to the volcanic rocks of the Xiong'er Group.

熊耳期岩浆活动在华北陆块广泛分布，除了陕西宝鸡附近及山西吕梁地区的火山岩，还广泛分布1.75Ga前后的基性岩墙群、A-型花岗岩以及比熊耳群稍晚的斜长岩、奥长环斑花岗岩等(1.75-1.70Ga)和碱性花岗岩类(~1.65Ga)。

The Beilekuduke biotite granites in the study area have long been thought to be of S-type.

初步研究表明，长期以来被认为S型花岗岩的贝勒库都克黑云母花岗岩应为铝质A型花岗岩。

3Though the variety of the biotite content in granite is not very important to the influence of macroscopic peak strength of granite, from the microscopic view, a range still a demand attractor that it affect, the peak strength of granite is the highest when the biotite content is about 5%.

3花岗岩中云母含量的变化对花岗岩宏观峰值强度的影响虽然不是非常显著，但是，从细观角度考虑，其影响的幅度还是需要引起注意的，在云母含量在大约5%时，花岗岩的峰值强度最高。

The test results show that both the permeability of sandstone and that of granite with a single fracture declines with the increasing effective pressure, following the law of exponential decay. The permeability sensitivity of granite with a single fracture to effective stress is much stronger than that of sandstone, but the recovery capability of permeability of sandstone is more stronger than that of granite with a single fracture.

试验结果表明，在围压升降过程中，砂岩和单裂隙花岗岩的渗透率均随有效应力的增加呈负指数规律减小，但单裂隙花岗岩的渗透率对有效应力的敏感程度远大于砂岩，而砂岩渗透率的恢复程度则远大于单裂隙花岗岩。

The rock types,according to intrusive order from the earlier to the later, are diorite, porphyraceous granite, two mica granite and alkali feldspar granite.

按照由老到新的侵位顺序，岩石类型依次为：闪长岩、似斑状花岗岩、二云母花岗岩和碱长花岗岩。

In view of some disputes that have cropped up in the naming of A_type granite in China, this paper suggests that the term alkaline granitoids should be used to replace the name A_type granite.

针对目前国内A型花岗岩命名中出现的一些问题，建议以"碱性花岗岩类"一词代替A型花岗岩。

Calling the anti-granite campaign a major threat to the granite portion of the natural stone industry, Hogan said MIA has already invested $50,000 of unbudgeted funds to stem attempts to scare consumers about granite.

由于反花岗岩运动对花岗岩造成极坏的影响，吉姆说，美国大理石协会已经投入50000美金的应急基金，遏制对花岗岩的不实言论，消除消费者对花岗岩的恐惧。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

The feldspars from the γA1 and γAIIa show many clear metasomatic alteration features; the- refore, the authors genetically consider the albitized protolithionite granite and the albitized zinnwaldite granite to be metasomatic altered granites.

花岗岩中长石具有清楚的交代特征，晚期岩体中的钾长石的An和Ab组份十分低，斜长石中的An和OI组份也很低，说明钠长石化黑鳞云母花岗岩和钠长石化铁锂云母花岗岩为交代蚀变花岗岩。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
