Abstract: The distribution of magmatite is characterized obviously by a netlike feature that magmatic belts intersect conjugately,forming a series of the late-Paleozoic,Mesozoic and Cenozoic magmatic network systems. Magmatic networks are probably controlled by the plastic flow networks in the lower lithosphere,which result in upwelling of magma owing to shear deformation and friction thermal effect of plastic flow belts and the weakening and lightening of the intrabelt media. The driving boundaries and directions of driving forces of continental tectonic deformation and the paleo tectonic stress fields in the various geological periods are estimated in terms of the "plastic flow /magmatite" networks. Furthermore,the problems involving the evolution of the network tectonics and others are discussed in the paper.
