Statistical analysis of the granulometry curves. Statistical analysis of the whole set of granulometry curves. Panel c plots each region of interest along the first two axes of the principal component analysis. Colored dots correspond to sample regions shown in Fig. 6. (a–e) Synthetic curves curves corresponding to the reconstruction of the average curve \(\pm 2\sqrt{\lambda _{i}}\) the loadings are shown along corresponding axes (blue curves), exhibiting differences with the average size distribution (black curve). On the first axis, curves a, b hightlight differences in the position of the mode of the distribution. On the second axis, curves (d, e) hightlight the differences of proportion of cells with average size
