大陆块

Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.

本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究，获得如下重要认识：（1）发现辉石出溶结构，由此获得峰期变质温度为850 C，并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质；（2）通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因，进而确定该区不存在晚期角闪岩相变质作用；（3）在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩，为泛非构造热事件的碰撞造山成因提供了重要佐证；（4）对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期，～550 Ma，热事件结束于～500 Ma，年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象；（5）进一步确认了东南极内部普里兹带的存在，它属于冈瓦纳超大陆内部的第二条泛非期缝合带，据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成，而是多个不同块体拼合的结果。

This reflects that the continent is the piece-togrther block of many blocks and the continent was conserved, and evolved and suffered many times tectonic reworking, which made the integrated strength of the lithosphere with apparently differentness and variation in different tectonic units and different location of the same unit.

这也充分反映大陆是多块体的拼合体，长期被保存、演化，遭受多次构造变动使之总体岩石圈综合强度随不同的构造单元与同一单元不同构造部位具有明显的差异和多变，从而也反映了大陆形成、演化成因和结构与组成的特殊性与复杂性，区别于大洋岩石圈。

The stratigraphic sequences and sedimentological characteristics indicate that the main body of the Bayan Har Basin is composed of Triassic flysch sediments deposited in a foreland basin during the Triassic.

把造山带沉积学研究内容和内涵进一步扩展，放到全球的古地理格架中，从造山带和沉积盆地关系上研究中国南大陆的独特裂聚演化史，反映出中国南大陆与全球古地理对比既有同步性也有非同步性；进而提出泛华夏陆块群是全球古地理的一个重要组成部分。

Three problems are discussed in this paper.(1) The evolutio n of orogenic belt constitutes the main part of the global continental lithosphe re growth. The phenomena of continent connected but not united is a tectonic mar k, which indicates the amalgamated continents and the interjacent orogen did not complete the unified crotonization.

讨论了三个问题：(1)造山带的演化是全球大陆岩石圈演化的重要组成部分，大陆联而不合的现象是两拼接陆块与居间造山带未统一克拉通化的构造标志。

It underwent the collision event of the Southern China plate with the North China plate at early Triassic, overthrust napping event of continental, and continental spread structure event beginning at Cretaceous. I...

它已经历三迭纪早期华南陆块与华北陆块的碰撞事件、大陆逆掩推覆构造事件及后期白垩纪早期开始的大陆伸展构造事件，是我国华南陆块与华北陆块之间的重要过渡单元。

Two hundred million years ago , all the continents were parts of a single land mass called Pangaea .

两亿年以前，所有的大陆都是一整块叫做泛古陆的大陆的一部分。

On the background of collision between India plate and Eurasia plate and uplifting of Tibet, the viscosity lower crustal flow induced crust thicken extensively, and driven upper middleup crust break into some big and small subblocks. The continental deformation features in SYR, including remotion of rigid subblock through the movement of huge slip faults and extensive crustal thickening, are not fit "Crustal thickening" mode or "Continental extrusion" mode.

川滇地区的大陆变形特征既存在广泛的地壳增厚现象，同时在下地壳塑性流动的驱动下，中、上地壳破碎成大小不一的块体，变形特征表现出整体刚性，因而不能简单地套用"地壳增厚"或"大陆逃逸"模式。

Based on the above discussion, the authors hold that, being a part of Rodinia supercontinent and located at its edge, NCB seems not to connect with the SCB but is quite close to the Siberia block.

据此可以认为华北陆块是Rodinia超大陆的一部分，它位于超大陆的边缘，可以不与华南陆块紧邻，而与西伯利亚陆地较近。

With a dip angle between 15° and 30°, the uplift of an obducted plate during continental collision is much higher, and able to form a high mountain. The uplift is greatest with a dip angle of 15°; whereas with a dip angle between 30° and 45°, the subduction depth of a plate is much deeper, and able to form a deep basin. The subduction depth is greatest with a dip angle of 45°. When the dip angle is equal to or greater than 75°, subduction and obduction movements between two continents become undistinguishable.

当断裂带倾角在15~30°时，两个大陆板块碰撞导致的仰冲板块一侧隆升高度相对更大，利于形成高大的山脉，其中以15°倾角对应的仰冲板块一侧隆升最高；当断裂带倾角在30~45°时，两个大陆板块碰撞导致的俯冲板块的俯冲深度相对更深，利于形成深陷的盆地，其中以45°倾角对应的俯冲陆块一侧俯冲最深；当断裂带倾角≥75°时，两个大陆板块之间的相对俯冲和仰冲作用变得不明显。

China big six cotises often already return to son to ride a three-wheeled cart call sell a form the big cake up glues raisin to make out colorful inferior food, few year ago I big six some cotises see in China a miss say that buys two dollars of, that time son but sliced the thing of more than 70 dollars for her, the miss doesn't want and return to son to lean on person's many power many don't let that miss walk.

中国大陆城市常有回子骑三轮车叫卖状似大蛋糕上粘葡萄干做得花花绿绿的劣质食物，数年前我在中国大陆某市见一姑娘说要买两块钱的，那回子却给她切了七十余块钱的东西，姑娘不要，回子倚人多势众就不让那姑娘走。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
