By research of granulite terranes and granulite xenoliths in volcanic rocks, composing and structure of deep substance in the earth could be realized directly.

通过麻岩地体以及火山岩中麻岩捕掳体的研究,使人们对地球深部的物质组成和结构有了直接的了解。

Characteristics of these two kinds of spinels not only indicate that the whole terrain underwent granulite facies metamorphism but also provide direct mineralogical evidence for the argument that Yushugou ophiolite suite of granulite facies lies in an environment of oceanic basin.

这两类尖晶石的特征一方面说明该地体遭受了麻岩相的变质作用改造,另一方面也提供了榆树沟麻岩相蛇绿岩套属洋盆构造环境的直接矿物学证据。

The mineral assemblages of the granulite are clinopyroxene, orthophyroxe, biotite, plagioclase, amphibole, quartz. According to the results of mineral electron probe analyses, the formation conditions of granulite are discussed and P-T conditions are calculated.

根据麻岩的主要组成矿物单斜辉石、斜方辉石、黑云母、斜长石、角闪石的电子探针分析结果,重点讨论了各主要造岩矿物的形成条件,并对麻岩形成的温压条件进行了初步计算。

The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的,镍和金在地幔岩包体中含量最高,铝在玄武岩及镁铁质麻岩包体中最高,而钨在长英质麻岩和花岗岩类包体中含量最高。

The results show that the formation of granulite have two stages: early granulite-facies rocks formed under the conditions of 0.88~1.1GPa and 880~890℃; the later amphibole-facies retrogressive metamorphism paragenesis formed under the conditions of 0.30~0.37GPa and 620~640℃, belonging to a typical low-pressure type.

结果表明:麻岩形成经过两个阶段,麻岩形成于0.88~1.17GPa,880~890℃条件下,角闪石-斜长石退变组合形成温度620~640℃,压力0.30~0.37GPa。

The SDB eclogites, on the other hand, were strongly overprinted by a high-pressure granulite-facies metamorphism under conditions of p=1.9~2.0 GPa and T=873~948℃, followed by temperature and pressure decrease to the amphibolite-facies. The process of temperature increase with decreasing pressure from UHP eclogite to high-pressure granulite suggests that the SDB eclogites exhumed at low speed and underwent strong thermal relaxation at a level of crust-mantle transition or thickened lower crust.

都兰南带榴辉岩折返过程中经历了高压麻岩相变质的改造,高压麻岩阶段的p-T条件为p=1.9~2.0 GPa,T=873~948℃,并进一步经历了角闪岩相退化变质,说明都兰南带榴辉岩折返速率较慢,发生了壳幔过渡带层次的强烈热松弛。

These results indicate that both the second type leucosome in the biotite gneisses and the first type leucosome were produced synchronously in the Paleoproterozoic granulite-facies metamorphism, and that both the melt-derived and the metamorphic Paleoproterozoic zircons suffered significant lead-loss in the Triaasic, suggesting that both felsic granulite and biotite gneisses be responses to the Triassic deep subduction event.

这表明,第二类浅色体和第一类浅色体都是古元古代麻岩相变质作用同期深熔产物。古元古代熔体结晶和变质结晶锆石在三迭纪发生了严重的放射性成因铅丢失,可反映长英质麻岩和黑云母片麻岩都响应了三迭纪深俯冲事件。

Mafic granulite and gabbro xenoliths are also found in the same kimberlitic pipes from the Eastern-North China platform, and suggest that multi-accretion events took place. The gabbro was formed lighly earlier with the host kimberlite. The underplating of the mafic magmas was related to the continental orogeny in the late middle-Ordovician Period.

金伯利岩中强烈变质的基性麻岩以及变质不彻底的粗辉长岩在同一岩管中共存,表明华北古老岩石圈地幔所发生的多次增生作用事件,特别是后者的变质不彻底变质作用暗示其形成时代与金伯利岩相近,这种基性岩浆的底侵作用与华北地台中奥陶世晚期的造陆抬升有关。

And with decrease in light intensity,the shape of palisade mesophyllchanged from column into invert pyramid.The higher proportion of granum thylakoid,more granum in one ganum thylakoid and lower ratio of chlorophyll a to chlorophyll bwere also the responses of leaves to shading.

在庇荫环境中,栅栏组织薄壁细胞由全光的柱状变成倒锥形、叶绿素a/b率显著降低、叶绿体中基类囊体所占的比例提高、每个基类囊体垛的片层数量增加等,也是幼树提高叶片对弱光利用能力的主要标志。
