大地构造和海陆起源的内波假说（Ⅱ）──建立假说的大地构造学与运动学基础

INTERNAL WAVE HYPOTHESIS FOR GEOTECTONIS(Ⅱ):Geotectonical and kinematical foundations of establishing the hypothesis

介绍建立大地构造内波假说的根据，即：（１）全球海陆分布的低阶球谐特征；（２）全球大洋中脊体系的存在；（３）大陆永存及生长的事实；（４）地壳均衡及莫霍面的化学分界面性质；（５）地槽活动的现象、规律等。在分析以在事实的基础上，研究了大地构造运动中主要的物质运动过程，认为从薄地壳底部向厚地壳底部迁移的地壳物质流，引起地壳厚度的自激波动，推动地槽运动和大陆生长。

The foundations of internal wave hypothesis are:(1).low order spheric armonic characteristics of global distribution of continents and oceans;(2). global midoceanic ridge system;(3). ever lasting continental crust and its growth in geohistory;(4). crust isostatic and (5). regular patterns of geosynclinal movement. Studying these facts, the author presents the kinematics for geotectonic movements, and there is driving material flow: lower crustal material from thin crust bottom moves into thick crust bottom.The material flow causes self-activating undulation of crustal thickness and drives geosynclinal movement and continental growth.
