中国地区水平地壳形变模型的建立

我国大陆板块是欧亚大陆板块的重要组成部分,其板块运动剧烈,地质构造复杂,是全球研究板块运动的重要地区。本文通过对各个块体分别建模和解算,得出结论:中国地区除东北块体相对于欧亚板块不动外,其他块体均有不同程度的形变运动,东部形变较小,西部形变较大;华北块体总体上以大约6mm/a的速率向东运动;华南块体以约5~8mm/a的速率向东南方向运动;新疆块体以约10~15mm/a的速率向北东方向运动;西藏块体也向北东方向运动,但运动速率从南到北逐步减少。

Establishment of China horizontal crustal deformation models

Chinese mainland block,as an important component of Eurasia plate,with intense crustal movement and complex geological structure,has always been a focus area in global plate research.This paper gives every sub-block of Chinese mainland blocks a specific model and corresponding calculation.The conclusion shows that all sub-blocks but the northeastern China block have respective deformation movement at different levels and deformations in the eastern part of China are greater than those in the west.Generally ...
