WebSorting refers to the range of grain sizes in a sediment deposit or in a clastic sedimentary rock (Figure 5.3.5). Poorly sorted sediments contain a wide range of grain sizes. Deposits … WebTop: 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. Clasts with sharp edges and corners are angular. Clasts with smooth surfaces are rounded.

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). WebSorting.

WebSedimentary rocks generally have porosities in the range of 10% to 30%, some of which may be secondary (fracture) porosity. The grain size, sorting, compaction, and degree of cementation of the rocks all influence primary porosity.
