Most of U-deposits of China, specially the large U-deposits, aresimilar to the U-deposits of many countries. There are close relationsbetween their formation, distributions of time and space and thetectono-magmatic activation of crust. The tectono-magmatic activationdiscussing in this paper (the following called activation for short) isonly confined to the activation after geosyncline stage or the consolida-tion of platform. As a result, the palingenetic geosyncline and medianmassif also belong to the discussing scope. The tectono-magmatism ofgeosyncline stage itself and its relevant U-deposits do not belong to the Most of U-deposits of China, specially the large U-deposits, aresimilar to the U-deposits of many countries.
