| 1 | 青藏高原东部上地幔各向异性及相关的壳幔耦合型式显示文摘对国家数字地震台网和云南、四川、甘肃、青海区域数字地震台网,以及布设在川、滇、藏地区的宽频带流动地震台网共116个台站所记录的远震SKS波形资料作偏振分析,采用叠加分析方法求得每一个台站的SKS快波偏振方向和快慢波的时间延迟,获得青藏高原东部及其邻近地区的上地幔各向异性图像.将该地区全球定位系统(GPS)的观测结果与上地幔各向异性分布相结合作地壳一地幔耦合变形的分析,研究表明青藏高原内部和高原外部的云南地区具有不同的壳幔变形特征,在高原的东缘地区(大致位于川滇西部的26°-27°N之间)存在一个壳幔变形的横向过渡带.过渡带以南地区的快波偏振方向从滇西南的S60°-70°E逐渐转变到滇东南的近东西向,以北的滇西北部和川西南部,快波偏振方向为近似的南北向.高原内部表现为强壳幔耦合型,高原外部则属于壳幔解耦型.这一横向过渡带与地表的断裂走向不一致,但在地壳和上地幔,其地球物理场(如:地壳厚度,布格重力异常和构造应力方向等)都具有横向过渡的特征.该横向过渡带邻近东喜马拉雅构造结,在板块边界动力学上有着重要的意义. | 王椿镛 常利军 吕智勇 秦嘉政 苏伟 Paul Silver Lucy Flesch | 2007 | 中国科学(D辑)2007,37,4: | 68 |
| 2 | Seismic anisotropy of upper mantle in eastern Tibetan Plateau and related crust-mantle coupling pattern显示文摘By using the polarization analysis of teleseismic SKS waveform data recorded at 116 seismic stations which respectively involved in China National Digital Seismograph Network, and Yunnan, Sichuan, Gansu and Qinghai regional digital networks, and portable broadband seismic networks deployed in Sichuan, Yunnan and Tibet, we obtained the SKS fast-wave direction and the delay time between fast and slow waves of each station by use of the stacking analysis method, and finally acquired the fine image of upper mantle anisotropy in the eastern Tibetan Plateau and its adjacent regions. We analyzed the crust-mantle coupling deformation on the basis of combining the GPS observation results and the upper mantle anisotropy distribution in the study area. The Yunnan region out of the plateau has dif-ferent features of crust-mantle deformation from the inside plateau. There exists a lateral transitional zone of crust-mantle coupling in the eastern edge of the Tibetan Plateau, which is located in the region between 26° and 27°N in the west of Sichuan and Yunnan. To the south of transitional zone, the fast-wave direction is gradually turned from S60°―70°E in southwestern Yunnan to near EW in south-eastern Yunnan. To the north of transitional zone in northwestern Yunnan and the south of western Sichuan, the fast-wave direction is nearly NS. From crust to upper mantle, the geophysical parameters (e.g. the crustal thickness, the Bouguer gravity anomaly, and tectonic stress direction) show the feature of lateral variation in the transitional zone, although the fault trend on the ground surface is inconsis-tent with the fast-wave direction. This transitional zone is close by the eastern Himalayan syntaxis, and it may play an important role in the plate boundary dynamics. | Paul SILVER Lucy FLESCH | 2007 | Science China Earth Sciences2007,50,8: | 33 |
| 3 | 中国大陆上地幔各向异性和壳幔变形模式显示文摘近10年来,中国布设的宽频带地震台站大幅度增加.宽频带地震记录中含有大量的剪切波分裂信息,它在揭示中国大陆上地幔的各向异性特征起重要作用.本文对这些台站的远震SKS和(或)SKKS记录,采用最小切向能量的分析方法,确定各台站剪切波分裂的快波偏振方向和延迟时间.此外,还收集了前人在中国大陆及其周边地区的剪切波分裂研究的部分结果,形成拥有1020个剪切波分裂参数对的数据集.这些分裂参数展示了复杂的上地幔各向异性图像.统计分析表明,中国大陆存在较强的上地幔各向异性,平均的剪切波时间延迟为0.95 s,其中西部地区为1.01 s,东部地区为0.92 s.西部地区的各向异性强度略大于东部地区.在大尺度意义下,青藏高原及天山地区,其SKS波分裂和地表变形数据共同支持岩石圈变形模式,即地壳与岩石圈地幔是连贯变形的;东部地区的平均快波偏振方向近似平行于绝对板块运动方向,上地幔各向异性归因于软流圈流动.中部的鄂尔多斯至四川盆地一带为东、西部两种变形模式的过渡带,各向异性结构较为复杂,表现为'化石'各向异性和(或)双层各向异性.印度板块和欧亚板块的碰撞是中国大陆西部上地幔各向异性的主要影响因素,东部地区则与太平洋板块和菲律宾板块向欧亚板块俯冲有关. | 王椿镛 常利军 丁志峰 刘琼林 廖武林 Lucy M FLESCH | 2014 | 中国科学:地球科学2014,44,1: | 31 |
| 4 | Upper mantle anisotropy and crust-mantle deformation pattern beneath the Chinese mainland显示文摘Over the past 10 years,the number of broadband seismic stations in China has increased significantly.The broadband seismic records contain information about shear-wave splitting which plays an important role in revealing the upper mantle anisotropy in the Chinese mainland.Based on teleseismic SKS and SKKS phases recorded in the seismic stations,we used the analytical method of minimum transverse energy to determine the fast wave polarization direction and delay time of shear-wave splitting.We also collected results of shear-wave splitting in China and the surrounding regions from previously published papers.From the combined dataset we formed a shear-wave splitting dataset containing 1020 parameter pairs.These splitting parameters reveal the complexity of the upper mantle anisotropy image.Our statistical analysis indicates stronger upper mantle anisotropy in the Chinese mainland,with an average shear-wave time delay of 0.95 s;the anisotropy in the western region is slightly larger(1.01 s)than in the eastern region(0.92 s).On a larger scale,the SKS splitting and surface deformation data in the Tibetan Plateau and the Tianshan region jointly support the lithospheric deformation mode,i.e.the crust-lithospheric mantle coherent deformation.In eastern China,the average fast-wave direction is approximately parallel to the direction of the absolute plate motion;thus,the upper mantle anisotropy can be attributed to the asthenospheric flow.The area from the Ordos block to the Sichuan Basin in central China is the transition zone of deformation modes between the east and the west regions,where the anisotropy images are more complicated,exhibiting'fossil'anisotropy and/or two-layer anisotropy.The collision between the Indian Plate and the Eurasian Plate is the main factor of upper mantle anisotropy in the western region of the Chinese mainland,while the upper mantle anisotropy in the eastern region is related to the subduction of the Pacific Plate and the Philippine Sea Plate beneath the Eurasian Plate. | WANG ChunYong CHANG LiJun DING ZhiFeng LIU QiongLin LIAO WuLin Lucy M FLESCH | 2014 | Science China Earth Sciences2014,57,1: | 18 |
| 5 | 青藏高原东部及其邻区力学耦合的岩石圈变形模式显示文摘根据青藏高原东部及其邻区布设的143个宽频带固定和流动地震台站的远震记录的SKS波分裂分析获得了各台站的快波偏振方向和快慢波之间的时间延迟。SKS分裂分析结果总体上反映了高原东部的上地幔物质流动方向,即高原内部表现为环绕喜马拉雅东构造结的顺时针旋转。在造山运动过程中有关岩石圈地壳和地幔力学耦合的造山变形方式,用从GPS和第四纪断裂滑动速率数据确定的地面变形场和由地震波各向异性数据推断的地幔变形场联合分析来定量求得。在青藏高原东部和云南、四川等地区新近快速增加的GPS和SKS波分裂观测数据,提供了对青藏高原岩石圈地幔实际变形方式的检验。这些新的数据不仅加强了高原内部力学耦合岩石圈的证据,而且也解释了高原外部相同的耦合特征。文中引入简单剪切变形和纯剪切变形的概念,用于解释高原内外不同的耦合变形特征。青藏高原和周围区域力学耦合岩石圈的垂直连贯变形有两个方面的大陆动力学含义:第一,岩石圈垂直强度剖面被一个重要的条件所约束,即要求与重力势能变化相关的应力能够从地壳传递到地幔;第二,青藏高原各向异性的空间变化反映了一个岩石圈变形的大尺度模式,以及从高原内部的简单剪切变形向高原外部的纯剪切变形的过渡带。文中提出的力学耦合岩石圈变形模型与当前已有的多种造山运动变形模型具有不同的变形含义,因此,地幔变形在青藏高原隆升过程中起主要作用。 | 王椿镛 常利军 苏伟 楼海 P.
