Sandur or outwash plain is formed of glacial sediments deposited by meltwater outwash at the end or snout of a glacier. Sandurs consist of sand and gravel that the glacier has grinded from the underlying rock surface as it flows.

WebGrain 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.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.
