The data set of various elements’ abundance is taken as an abundance sequence, and fractal dimension (box dimension) is used in the study of elemental abundance of the granitoid in China. The authors demonstrated a new elemental abundance method with a basis of frequency characteristics. It can be concluded that elemental abundance sequence of the granitoid may operate structural evolution in some form, and conventional log-normal distribution fails to describe the frequency laws. However, the cumulative summation and error obey fractal distribution. Herein, descending order of the fractal dimension, which is of important geochemical significance, corresponds to the degree of chemical evolution of the observed sequence, so do the results of cluster analysis.
