Multi-layer Tectonic Model for Intraplate Deformation and Plastic-Flow Network in the Asian Continental Lithosphere

In a large area of the east—central Asian continent there is a unified seismic network system composed of two families of large—seismic belts that intersect conjugately. Such a seismic network in the middle—upper crust is actually a response to the plastic flow network in the lower lithosphere including the lower crust and lithospheric mantle. The existence of the unified plastic flow system confirms that the driving force for intraplate tectonic deformation results mainly from the compression of the India plate, while the long-range transmission of the force is carried out chiefly by means of plastic flow. The plastic flow network has a control over the intraplate tectonic deformation.

亚洲大陆岩石圈多层构造模型和塑性流动网络

中、东部亚洲大陆的广大地区存在着由两族大型地震带共轭相交而成的统一地震网络;位于中、上地壳的这种地震网络,实际上是岩石圈下层(含下地壳和岩石圈地幔)塑性流动网络的一种响应。统一塑性流动网络系统的存在,证实了板内构造变形的驱动力源主要来自印度板块的碰撞推挤,而作用力的远程传递主要借助于网络状塑性流动。塑性流动网络对板内构造变形起着控制作用。
