摘要
本文对地壳构造运动、深部地球物理特征的分析和研究结果表明,深源地幔物质流和浅源地幔物质流的运移状态及其组合型式,以及它们与地壳下界面形状的相对关系,是影响大地构造运动和地壳形变的主要因素。并由此说明了某些地区大地震活动比较集中和易于发生的原因,以及它们所对应的深部地球物理背景。
Bt studying the deep geophysical background of the crustal motion, it shows that the movement style of deep mantle flow and shallow mantle flow, their composition form and the relation between Moho shape and mantle movement are the main factors to affect the crustal motion. From this result, it can be found the reason of the occurence of strong earthquakes often in some areas and the background of deep geophysics in this area.
