洋盆

This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

这种类型的断层活动是由伸展作用造成的，常常在美国西部的盆岭省以及海底洋岭系统中观测到。

This ophiolitic tectonic melange is composed of some complex slabs from different tectonic settings and structural levels, which underwent different metamorphism with different PTt paths and reworking. The PTt path study in this paper reveals that Sanchazi metagabbro from Mian-Lue Suture zone of Qinling orogenic belt underwent two metamorphic and tectonic stages.

勉略带是近年来秦岭造山带研究中揭示出来的代表晚古生代小洋盆的缝合带，组成复杂，它们经历了不同的变质、变形改造，构成了不同构造背景、不同构造层次、不同物质组成、具不同PTt轨迹的蛇绿构造混杂带。

The major mechanism of formation of the ophiolites and the podiform chromite diposits in the Western Zhungeer area includes partial melting of the primary pyrolite and differentiation of the melt-out materials after they intruded. The differences between the two ophiolite types are related to the degree of partial melting of the pyrolite and depth of formation of magma chambers as well as oxidation state of the magmas.

对西准噶尔地质条件的分析表明：西准噶尔的蛇绿岩与铬铁矿形成于弧后扩张盆地环境，洋壳形成阶段从晚寒武直至中泥盆统，而盆地沉积阶段则从中奥陶延续到中石炭；洋壳推覆时代不一致，在唐巴勒为早志留，玛依勒山为晚泥盆，达拉布特与和布克赛尔则晚于中石炭。

I-type granite occurs on north of HongliugouLapeiquan Fault, its chemical composition is similar to that of trondhjemite arisen by Barker (1979), maybe also a product of subduction and collision of oceanic basin in early Paleozoic.

根据SiO〓-Al〓O〓和SiO〓-FeO〓/图解判别显示造山后花岗岩的特征；后者分布在红柳沟—拉配泉断裂以北，其成分与巴克尔1979年提出的奥长花岗岩的成分非常相似，也可能是区内早古生代洋盆俯冲碰撞的产物。

As board piece dive continuity, basin of the arc before slimy basin world appeared in, formed copper - lead - bed of zincic much metal.

早泥盆世，由于古亚洲洋板块的俯冲，在阿尔泰南缘形成了一系列陆缘断陷盆地，并伴随以铅、锌、铜、铁多金属为主的矿化；同时，俯冲的古亚洲洋板块发生部分熔融，形成了埃达克岩及和其有关的铜矿床。

The Ocean basin,represented by Guanzizhen-Wushan ophiolite,subducted fromsouth to north in early Ordovician.

关子镇—武山蛇绿岩代表的洋盆于早奥陶世发生由南向北的俯冲消减。

The Central Orogenic Belt originally consisted of a series of microplates plus two rows of micro_oceans of different stages located respectively to the south and north of the microplates.

中央造山带原型是由一列微板块加上分别位于其北面和南面的两列不同时期的小洋盆组成。

This suggests that subduction of a paleo-ocean basin occurred between the Paleoproterozoic North China craton and Qaidam craton.

因此推测斜长角闪岩的原岩为不同程度部分熔融的岩浆弧作用的产物，说明在古元古代华北克拉通和柴达木克拉通之间存在古洋盆的俯冲消减。

Continental margin and ocean basin.

大陆边缘和洋盆。

The Xinyang-Yuanlong large-scale shear zone belongs to the eastern part of Qilianorogenic belt,which is mainly known for a intracontinental rifting-small ocean basin coveredby Hongtubao-Huluhe metamorphism basaltic rock.In the north of the shear zone,detritalrock of Chenjiahe group sedimented in forearc basin and island-arc volcanics of Chenjiahegroup in late Ordovician and island-arc granites of Yanjiadian formation and Huangmenchuanformation outcrop in order.

新阳—元龙大型韧性剪切带以北属祁连造山带东段，发育有以红土堡—葫芦河变基性火山岩为代表的陆内裂陷—小洋盆，北侧依次出露有弧前盆地沉积的晚奥陶世陈家河群碎屑岩组、岛弧环境的晚奥陶世陈家河群火山岩及以阎家店、黄门川为代表的岛弧型花岗岩类。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
