频谱分析法在反演造山带地形高差演化中的应用——以中国大别山、米仓山和美国内华达山脉为例: 近年来迅速发展的低温热年代学已极大改善了人们对地壳内(1～6 km)隆升和剥蚀过程的认识。然而在实际工作中,样品的采集除了受到气候、地理环境等恶劣条件的制约以外,在对低温热年代学数据进行解释或以此计算造山带的隆升剥露速率...; 苏哲刘静张鲁新王二七; 关键词：古地形构造地貌学; 文献传递

青藏高原中部Quasi-Love波的识别及其转换点揭示的东西向方位各向异性变化: 2009年; 目前人们利用4种基本的地震波现象研究地震各向异性,如横波双折射、面波散射、与传播方向有关的走时异常和PS转换波震相.本文利用面波散射产生的Quasi-Love(QL)波研究青藏高原上地幔顶部的各向异性结构特征.首先利用中国地震台网昌都(CAD)台记录的地震波形资料识别出产生QL波的路径,并利用合成地震记录和垂直偏振极性分析证实所观测到的为QL波,而不是高阶振型的Rayleigh波或其他体波震相;然后由Rayleigh波、Love波和QL波的群速度估算了各向异性结构横向变化的转换点;不同周期时,转换点的位置不同.这种频率依赖性还需要进一步的模拟研究.Love波向Rayleigh波耦合(产生QL波)的转换点位置揭示了青藏高原面波方位各向异性变化特征,并以南北向构造带的东西分段性、上地幔流引起的地球内力诱导岩石形变解释了青藏高原各向异性的东西向差异性.; 张素芳; 关键词：青藏高原中部各向异性

接收函数方法估计Moho倾斜地区的地壳速度比: ＜正＞地壳速度比（Vp/Vs）是研究地壳属性的重要参数,接收函数方法在估计这一参数方面具有独特的优势。构造活动区的复杂力系作用往往使Moho界面发生变形,局部表现为倾斜。通过模型分析显示,当Moho界面倾角＞4°时,估计...; 张洪双田小波滕吉文; 文献传递
