Sorting is a term usually applied to sediments or sedimentary rock, and describes the degree of uniformity of grain size. The degree of sorting depends upon how much transport the sediment has undergone. Well-sorted sediments have grains of similar size, and are the result of much sediment transport and earth processes which segregated the ...

The transition of sandstone into quartzite is a gradual process. A single rock unit such as the Tuscarora Sandstone might fully fit the definition of quartzite in some parts of its extent and be better called "sandstone" in other areas. Between these areas, the names "quartzite" and "sandstone" are used inconsistently and often guided by habit.
