| Abstract: | The tectonic stress field and seismic tectonics in the North China region are investigated in terms of the "plastic-flow network and multi-layered tectonic deformation" model for continental dynamics. It is presented in the model that in consideration of the basic state of the transition of deformation regime from brittle to ductile with increase of the depth, the lithosphere is divided into several tectonic deformation layers, i.e. the ductile lower lithosphere (including the lower crust and lithospheric m |
