Rock fragment explained

Rock Fragment
Type:Sedimentary particle

A rock fragment, in sedimentary geology, is a sand-sized particle or sand grain that is made up of multiple grains that are connected on the grain scale. These can include grains which are sand-sized themselves (a granitic rock fragment), or finer-grained materials (shale fragments).[1] This definition is used for QFR ternary diagrams, provenance analysis, and in the Folk classification scheme, mainly in sandstones.
