Sorting is the variability in grain size in a clastic sedimentary rock. This parameter measures how well a sediment has been ‘sorted’ by the process that transported it. A sediment can be: – very well sorted: nearly all grains have the same size. – well sorted: most grains fall in a single grain size class with few outliers.
