Poorly sorted sediment
WebJan 15, 2024 · Sorting is the range of grain sizes that occurs in sedimentary materials. Well-sorted materials have grains of the same size, while poorly sorted materials have grains of many sizes. Permeability decreases as the degree of sorting varies from good to poor because small grains can fill the spaces between large grains. WebFigure 8.19 Top: Sorting of grains, ranging from well sorted where the grains are similar in size, to poorly sorted, where the grains vary greatly in size. Bottom: Rounding refers to how smooth or rough the edges of a clast are. ... the sediment is said to be well sorted. If the grains vary substantially in size, the sediment is poorly sorted.

In sedimentary rock and sediments, controls on porosity include sorting, cementation, overburden stress (related to burial depth), and grain shape. Poorly sorted sedimentary deposits, in which there is a wide distribution of grain sizes, typically have lower porosity than well-sorted ones (Figure 11). how many were killed at sandy hookSorting describes the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks.
