Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials.

Grain size is the average diameter of individual grains (particles) of clastic sediments and rocks. It is also known as the particle size. Grain size represents a fundamental character of clastic …

Grain size is the average diameter of clasts (particles) of clastic sediments and rocks. Grain size is the primary parameter in sedimentary geology to divide clastic rocks and sediments in …

Dec 17, 2025 · The grain-size distribution of sediments in many settings commonly appears to be inherited or to exhibit as much variation within a single environment as between different ones.

Grain size refers to the diameter of individual particles or crystals in sedimentary rocks and sediments, which plays a crucial role in their formation and classification.

Grain size is a central factor in any discussion of nanostructured metals, yet too often, it is not characterized in sufficient detail. In most published papers, authors simply report an “average …

Sorting is a measure of the uniformity of grain size in a specimen. A well sorted sample will have relatively uniform grain size whereas a poorly-sorted sample has a wide range of grain sizes.

Feb 13, 2025 · Grain size classifies sedimentary particles from coarse gravel to fine clay using scales like Udden’s and Atterberg’s. Analysis methods include direct measurement, sieving, …
