测量了喜马拉雅东构造结59个新的地震台站的SKS/SKKS波分裂参数,并结合前人在该区域得到的69个台站的横波分裂结果,以此来分析东构造结的地幔变形场特征。密集各向异性测量结果显示,快波方向在东构造结核心部位的南迦巴瓦为NE—SW方向,其周边地区为绕南迦巴瓦顺时针旋转的特征。我们基于全球定位系统(GPS)和第四纪断层滑动速率测量数据确定了一个连续的地表变形场,并以此来模拟每个台站预测的快波方向。通过快波方向的测量值和预测值对比分析,南迦巴瓦11个台站快波方向的测量值和预测值的平均角度差达60.8°,而其周边地区的角度差只有11.7°,这说明除南迦巴瓦以外,东构造结岩石层变形特征主要为垂直连贯变形模式,而南迦巴瓦不符合垂直连贯变形模式。地幔各向异性的复杂性和地表观察表明南迦巴瓦应变场的局部变形岩石层可能与印度板块在其下方俯冲作用有关。

上世纪90年代,中国大陆及其周边地区开始了上地幔各向异性研究,并获得了一些成果。自2000年以来,我国在大陆地区建成了超过1200个的宽频带地震台站。基于这些台站的地震记录,利用剪切波分裂分析算法获得一大批远震事件的快波偏振方向和延迟时间,用于分析中国大陆上地幔各向异性。本文基于华南及印支地块的365个地震台记录的远震SKS和SKKS波形数据,用最小切向能量法确定每个事件的剪切波分裂快波偏振方向和快慢波时间延迟。计算结果表明,除四川盆地和雪峰山构造带外,华南及印支地块快波方向一致地指向WNW-ESE,接近于绝对板块运动的方向。已有的地球物理研究表明,四川盆地和雪峰山构造带下方具有巨厚的岩石圈,地幔各向异性可能主要来自岩石圈。雪峰山构造带的NE向快波方向与构造带走向一致,意味着该岩石圈保持了早中生代陆内碰撞造山所产生的"冻结"各向异性。综合几个方面的证据,我们认为华南地区地震各向异性主要来源于岩石圈下方的软流圈流动。华南地区的快波偏振方向与绝对板块运动方向的一致性表明地幔各向异性产生于岩石圈与软流圈之间变形的差异,即现今的软流圈流动。但是,华南地块的快波偏振方向与绝对板块运动方向方向存在5°的系统偏差,预示华南及印支地块下方可能存在附加的地幔流。对已有的GPS数据和新近获得的地震各向异性结果作联合分析推断华南地区存在活动地幔流结构,它以5mm/yr的速度朝西南向流动,指向缅甸/巽他俯冲板片。这一活动地幔流可能是源于缅甸/巽他俯冲板片回卷—后退的激发,它将板片上方的软流圈上部朝西南方向拖曳。Becker and Faccenna(2011)和Ghosh and Holt(2012)先后使用全球层析成像和地幔对流模型预测在亚洲的地幔流,但是这一大尺度的地幔流并没有预测出华南及印支地块下方的正确方向。在印度洋与欧亚板块碰撞过程中,印度洋板块向北的驱动在印度洋东经90o海岭的两侧分成两种不同的碰撞方式,海岭西侧以碰撞造山为主形成青藏高原,东侧则由于板块的连续俯冲在印支地块下方形成了缅甸/巽他俯冲带。这两种碰撞模式导致环绕东构造结壳幔变形的复杂性。该壳幔变形模式由两部分组成:西部和北部(高原内)的岩石圈垂直连贯变形和东部(华南和印支地块)的软流圈流动。活动地幔流是环绕东构造结各向异性的重要组成部分。

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.

The solid state synthesis of the phase"Ce_(3)NbO_(7+δ)",from stoichiometric quantities of CeO_(2)and Nb_(2)O_(5),was investigated under air atmosphere,as previously described by Zhang et al.(Journal of Rare Earths,2007,25,730-733),A combination of powder X-ray diffraction,scanning electron microscopy with energy dispersive X-ray analysis,and laboratory Ce L_(3)X-ray absorption spectroscopy,demonstrates the product of the reaction to be a mixture of CeO_(2)and CeNbO_(4).These data,and reexamination of the published X-ray diffraction data of"Ce_(3)NbO_(7+δ)",are consistent with this phase in fact being CeO_(2).No evidence for the formation of a phase of composition"Ce_(3)NbO_(7+δ)"is found,by solid state synthesis under air atmosphere.
