Limestone Colors, Textures & Finishes | Indiana Cut Stone
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.

Limestone rocks are mainly calcium carbonate (CaCO 3), and are the skeletal remains of marine organisms and chemical precipitates of CaCO 3.The principal agent of chemical weathering is carbonic acid (H 2 CO 3) in the soil solution.Because plant roots and decomposing soil organic matter release CO 2 to the soil pore space, the concentration of H 2 CO 3 in soil waters is generally greater than ...
