Parametric mapping of PCA scores. Color representations of parametric mappings obtained from granulometry curves within each region of interest. a Parametric mapping of the scores along the first principal component. b Parametric mapping of the scores along the second principal component. Red colors correspond to positive values, blue colors to negative values, and bright colors to values close to zero
