There are a large number of Neoproterozoic deformed-granites exposed in the eastern part of the Beihuaiyang belt. It is a great significance to know the magmatic evolution of the Beihuaiyang belt through the petrogenesis. In this paper,the petrogenic age and genetic type of deformed-granites in the north of Wanfo Lake were investigated through field geological survey,LAICP-MS zircon U-Pb isotopic dating and geochemical analysis. The results show that deformed-granites are mainly composed of quartz,potassium...
