Although the mineral composition varies slightly, limestones show great texture diversity. Limestone is usually classified depending on grain type and mud content. ... Oolitic Limestone: These rocks are sand-sized clasts consisting mainly of calcium carbonate with an ovate or spherical shape.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. Indiana Limestone has Consistent Color and Texture. Indiana limestone has an extremely consistent texture and color for a natural stone. Indiana limestone’s consistent coloring and grain makes it a perfect choice not only for new structures but also when matching existing stone for renovation projects that may take place decades after the original structure was built. Oolitic limestones are a type of sedimentary rock that are primarily composed of calcium carbonate (CaCO3) and small, spherical grains known as ooids. Ooids are typically 0.25mm to 2mm in diameter and are formed from concentric layers of calcium carbonate that build up around a central nucleus, such as a shell fragment or a grain of sand.
