中国天然地震探测深部构造的研究现状与发展
|
摘要
在青藏高原等地区为研究下地壳上地幔的构造特征，最近１０ ａ 投入了较大工作量的天然地震探测。它可以获得较大深度上的地震速度图像、上地幔的各向异性，划分出低速体低速层，为研究地球动力学特征提供了新的资料。随着仪器的发展完善，这种方法在我国深部研究中成为重要而且经济的手段。地震层析、接收函数的研究、以及剪切波分裂的分析都取得了很大的成绩。在这些方面还有许多工作要深入研究，继续深入发展具有重要意义。
Quite a large amount of teleseismic profiling has been conducted in the past 10 years or so in the Tibetan Plateau to study the lower crust upper mantle structure, yielding informative data for the geomechanic features ranging from the in depth seismic velocity image, upper mantle anisotropy and the identification of the low velocity body and layer. Along with the improvement in seismic equipment, the method has become the major means in the studies on deep seated structures in an inexpensive manner. Marked achievement has been gained in seismic tomography, the study of receiver functions and the analysis in shear wave splitting. However, room for further studies remains.
