| 摘 要： | Based on the data on plagioclase number of granitoids and whole.rock chemical analysis the author has proposed that the percentage of molecules of albite in the coexisting plagioclase and alkali-feldspar can be converted directly by petro-chemical approach. Then, the result is substituted into the formula of J. A. Whitney and J. C. Stormer, Jr. (1975, 1977) in order to work out the temperature during crystallization of the coexisting feldspars, which may represent the diagenetic temperature of host granitoids. Diagenetic temperature values computed by this method as described in the present paper are more accurate than thoes obtained by other geothermometries.
