| Abstract: | It is attempted to study the relationship between the composition of granitic melts and their U-producing potential through structural characteristics of melts, to analyse the controls of K, Na in melts over the uranium enrichment processes, and octahedral site, tetrahdral site and crystal field effect, and affection of O/Si ratio on mobility of uranium, and to discuss controlling factors of viscosity of melts. Based on these studies, the author has proposed a method for calculating the relative index of melt viscosity, and elaborated, in combination with examples, the significance and application of relative index of melt viscosity to geology, and summarized the criteria favourable for U-producing structural characteristics of granitic melts. |
