For example, very well sorted and rounded materials may suggest a source from an older sedimentary rock rather than from freshly exposed igneous rocks.
WebDetritus - the loose, fragmental debris produced by the mechanical breakdown of older rocks. Features of clastic sediments. Sorting - is the measure of range of particle size of sediments. A sediment having a wide range of particle size is said to be poorly sorted and if the range is small, the sediment is said to be well sorted.
