Summary:The activation history of certain regions of China, i.e. the SW margin of Alxa old land, northern Qilianshan and the Gangsu corridor regions, is divided into three periods: 1) reflex activation on the SW margin of Alxa old land, 2) reflex activation during P-T in all regions, and 3) a period of subsidence. Reflex activation on the SW margin of Alxa old land was mainly a tectonomagmatic activation. Reflex activation in the Qilianshan and Gansu corridor regions included reflex tectonomagmatic and tectonic-basin activation. Three characteristics of U mineralization in three regions are distinguished: 1) hydrothermal U mineralization mainly formed during reflex tectonomagmatic activation periods on the SW margin of Alxa; 2) hydrothermal U mineralization and epigenetic U mineralization during the P-T reflex activation period in Qilianshan and the Gansu corridor; and 3) different epigene and epigenetic U mineralizations developed in the subsidence period. The influence of tectonic activity on U mineralization is discussed. [P.Br.]
