Maturity (sedimentology)

In sedimentary geology, maturity describes the composition and texture of grains in clastic rocks, most typically  sandstones, resulting from different amounts of sediment transportation. A sediment is mature when the grains in a sediment become well-sorted and well-rounded due to weathering or abrasion of the grains during transport. There are two components to describe maturity, texture and composition.  Texture describes how rounded and sorted the sample is while composition describes how much the composition trends toward stable minerals and components.
