Roundness is an important indicator of the genetic affiliation of a clastic rock. The degree of roundness points to the range and mode of transport of clastic material, and can also serve as a search criterion in mineral exploration, especially for placer deposits. Alluvial debris in major rivers tend to exhibit a … See more Roundness is the degree of smoothing due to abrasion of sedimentary particles. It is expressed as the ratio of the average radius of curvature of the edges or corners to the radius of curvature of the maximum inscribed sphere. See more Abrasion occurs in natural environments such as beaches, sand dunes, river or stream beds by the action of current flow, wave impact, glacial action, wind, gravitational See more • Sorting (sediment) • Sphericity • Tumble finishing See more Rounding, roundness or angularity are terms used to describe the shape of the corners on a particle (or clast) of sediment.
