Examples of the artificial grain-size distributions and separation results. Examples of the artificial grain-size distributions used in the present study and separation results when the true numbers of components were a two and b four. The blue solid lines show the true normal distribution components. The red and green dashed lines show the components separated by the EM algorithm and their mixing curves, respectively. The values shown above each component are the mean grain sizes and the mixing proportions of the true and separated components (blue and red, respectively)
