Poorly sorted vs well sorted sediment
WebSorting refers to how much variation there is in grain sizes within a rock, and is characterized on a scale ranging from poorly sorted to well-sorted (Figure 1.1). For example, glacial ice can carry all particle sizes; hence, when glaciers deposit sediment it results in a poorly sorted sediment (a wide range of clast sizes). WebApr 17, 2024 · 1. n.

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.
