Sorting (sediment)

From Wikipedia, the free encyclopedia

Sorting indicates the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks. Poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance).

The degree of sorting may also indicate the energy and/or duration of deposition.
