the particle size classification for detrital rocks

SEDIMENTARY ROCKS

*This is the basis for the classification of sedimentary rocks. The name of the rock indicates how the rock formed. It attempts to delineate the conditions of deposition and the source of the sediments. 1. Clastic particles derived from the breakdown of pre existing rocks sedimentary, metamorphic or igneous. Clastic sediments make up 75

Grain size

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. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
