Despite the different initial distributions and particle sizes of the quartz sand and gravel, the measured PSD data that the values of fractal dimension exceed to 2.2 are shown to be strictly self-similar. Therefore the value of 2.2 can be considered as the lower limit of the fractal dimension of a fractal distribution.
