摘要：

Based on the data on plagioclase rumber of granitoids and whole-rock chemical analysis,the author has proposed that the percentage of molecules of albite in the coexisting plagioclaseand alkali-feldspar can be obtained by direct conversion through a petro-chemical approach.Then, the result is substituted into the formula of J. A. Whitney and J. C. Stormer, Jr. (1975,1977) to work out, the temperatures at which the coexisting feldspars ctystallized, i.e., the pos-sible rock-forming temperature of granitoids. Rock-forming temperature values computed bythis method as described in the present paper ate in good agreement with those by other geo-thermometries.
