An approach mainly based on mathematical morphology operators to compute the size distribution of the grains of sedimentary samples in-situ is presented in this paper. The methodology consists of the application of the concept of max-tree for a fast computation of the morphological openings that are capable of simulating the sieving process.Its validity is given by the high similarity of the granulometric curves computed on standard samples of sand with those obtained from the application of standard sieving procedures. Although this study presents preliminary results it already illustrates the vast capability of the method to compute the full size distribution curve rather than only the average size on images collected in-situ.
