查询词典 continental block

Combined the geological analysis with analogue modeling experiments,the evolution of the Yinggehai basin could be divided into four main stages:(1) Before 42Ma,controlled by the southeastward extension of the Beibu Gulf basin on the northern continental margin,the Yinggehai basin experienced dextral pull-apart.Bounded by NS-trending Yingxi fault,the transtensional areas mainly are the northwest part and along the eastern boundary of the basin.(2) From 42 to 21Ma,the development of the main rift body in Yinggehai basin was mainly controlled by the southward slip and clockwise rotation of the Indochina block along the Red River fault zone,and the sedimentation was strengthened due to the sinistral transtension.In the east,the subsidence is deepened due to the dextral transtension.(3) From 21 to 10.4Ma,the sinistral movement of the Indochina block slowed down to still.From 21 to 15.5Ma,the northwest part of the basin began to inverse locally because of post-rift thermal subsidence of the whole basin.(4) From 10.4Ma to present,the basin was affected by the dextral movement of the South China block along the Red River fault zone and thermal accident in a new phase at 5Ma.

结合地质分析和物理模拟实验，莺歌海盆地的演化大致可以分为以下4个主要阶段：早期(42 Ma以前)主要受到南海北部陆缘裂解造成的右旋转换伸展作用的影响，但影响范围较小，主要为莺歌海盆地西北部和东部边界。42～21 Ma期间，主要受控于印支地块左行走滑和顺时针旋转作用的影响，莺歌海盆地在此期间发育了主体裂陷体系，东侧受到右旋转换伸展应力场的叠加影响而导致沉降加强；21～10.4 Ma期间，受印支地块逐渐减弱直至停止的左行走滑作用的影响，盆地西北部在21～15.5 Ma期间发生局部反转褶皱，但盆地整体进入以热沉降为主的时期；10.4 Ma以后，盆地受华南地块沿红河断裂右旋走滑作用和5 Ma以后新一期热事件的影响。

The magmatic activity of collision granites provides the information about the tectonic dynamics from the continental margin epicontinental of the south of Erguna block in the Neo-proterozoic to Early Cambrian.

碰撞型花岗岩的岩浆活动提供了该区新元古代－早寒武世额尔古纳地块南部大陆边缘陆缘增生的构造动力学信息。

The geological and geophysical data show that in the lower crust of young continental tectonic units may occur pervasive, non-seismic, subhorizontal and ductile flow related to thermal softening. The laminar flow drives fault-block movement of the upper crust, results in the formation of orogenic belts and sedimentary basins, and causes coupling between ductile lower crust and brittle upper crust/mantle.

大量的地质和地球物理资料表明，年轻的大陆构造活动区的下地壳可能因热软化而出现透入性非地震式顺层韧性流动，这种下地壳层流作用驱动大陆上地壳发生地震式脆性断块运动，形成盆山格局，发生圈层耦合。

This paper discusses the structural characteristics of "block-zone mosaicking and multi-layer superimposition" of the continental crust of China and its multi-stage tectonic evolution.

中生代早期：因扬子地块向北西方向俯冲，造成了华北地块东部大陆岩石圈曾存在一次重要的加厚过程，随之而来的是俯冲板片的断离和岩石圈根的拆沉。

And then a local extension took place in the region of intra-Eastern Tethys when the India plate drifted to the north but suffered the resistance from the Lhasa block, contemporarily, the intra-oceanic subduction are triggered, subsequently, magmas derived from a partial melting of mantle wedge which suffered from the modification by subducted continental marginal clastics and oceanic sediments upwelled along the oceanic ridges, forming several small marginal basins during 120～128 Ma, and thus lead to the so-called SSZ-type oceanic crust.

于120～128Ma，一些规模较小的边缘洋盆形成，卷入陆缘碎屑和洋壳沉积的地幔楔发生熔融产生岩浆，沿着破裂的扩张脊上涌产生了具有TNT负异常的SSZ型新洋壳，期间产生了俯冲洋壳重熔作用，标志着年轻的热的洋壳俯冲形成的埃达克岩侵入于仁布SSZ蛇绿岩地幔橄榄岩中。

济阳坳陷正是在这个大地构造背景下，在前寒武系结晶岩和古生界碳酸盐岩及含煤碎屑岩组成的稳定地台基础上发展起来的中、新生代陆相断陷盆地，是渤海湾盆地内七大生油坳陷之一，并具有明显的复式成藏的特点，包括东营凹陷、沾化凹陷、车镇凹陷和惠民凹陷等次级构造单元，是胜利油田的主要探区。

Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5～+ 2.1, T_ = 1.0～1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4～18.9,~(87)Sr/~(86)Sr = 0.705～0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.

该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5～+2.1)、高T_(1.0～1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705～0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4～18.9，反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明，大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值；而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。
