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.

Sorting refers to how uniform the particles are in terms of size (Figure 12.1.3). If all of the particles are of a similar size, such as in beach sand, the sediment is well-sorted. If the particles are of very different sizes, the sediment is poorly sorted, such as in glacial deposits.

"WebSorting. Sorting is the variability in grain size in a clastic sedimentary rock. This parameter measures how well a sediment has been ‘sorted’ by the process that transported it. A sediment can be: – very well sorted: nearly all grains have the same size. – well sorted: most grains fall in a single grain size class with few outliers. " - Poorly sorted vs well sorted

[Geology] Well-sorted sediments are of similar size (such as desert sand), while poorly-sorted sediments have a wide range of grain sizes (as in a glacial till). A well-sorted sandstone tends to have greater porosity than a poorly sorted sandstone because of the lack of grains small enough to fill its pores.

WebWhat is the difference between a poorly sorted and well-sorted clastic sedimentary rock? Well-sorted sediment consists entirely of clasts that are the same size Poorly sorted sediment contains a mixture of clast sizes. What is the difference between conglomerate, sandstone, and shale? WebPoorly sorted sedimentary deposits, in which there is a wide distribution of grain sizes, typically have lower porosity than well-sorted ones (Figure 11). This is because the finer particles are able to fill in spaces between the larger grains.
