Thus most classifications require that the most significant sedimentary particle in the Rock be described. For instance, if a Rock is composed of ooids, it is termed and oolitic limestone. If the limestone also contains a minor element such as skeletal fragments, then it is called a skeletal-oolitic limestone. The Indiana Limestone Institute grade classifications are determined by how fine or coarse the grain particles and other natural characteristics that comprise the limestone. Oolitic and fossiliferous limestones appear in all grades of limestone. The structural soundness of each classification of limestone is essentially identical.Main page; Contents; Current events; Random article; About Wikipedia; Contact us; DonateHistory Original classification.
