The Dunham classification (Dunham, 1962[1]) did not consider grain size as a criterion for the description of carbonate lithologies. In an attempt to rectify this perceived deficiency, Embry & Klovan (1971[2]) introduced the terms rudstone (grain supported) and floatstone (matrix supported) for coarse-grained allochthonous carbonates. Following a survey of the use of the Dunham classification, Lokier and Al Junaibi (2016)[3] clarified the definition of a rudstone as "a carbonate-dominated rock where more than 10% of the volume is comprised of grains larger than 2 mm and these grains support the fabric of the rock."
