Limestones are formed by either organic or inorganic processes, and may be detrital, chemical, oolitic, earthy, crystalline, or recrystallized; many are highly fossiliferous and clearly represent ancient shell banks or … The rocks were deposited in a marine reef-flat environment protected from the open sea. Some examples of chemical sedimentary rocks are crystalline or fossiliferous limestone, chalk, chert, gypsum, rock salt and bituminous coal. The matrix that holds it all together is micrite. Like other limestones, fossiliferous limestone is composed of calcite and will dissolve in acid. Fossiliferous limestone - Wikipedia. Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces.The fossils in these rocks may be of macroscopic or microscopic size. They are classified into several groups according to their type of formation, composition or appearance. The facies of the fossiliferous Quilon Limestone in SW India is described for the first time in detail at the Padappakkara-type locality. It may be hidden with your walls, in the water you drink, the food you consume, or in the cosmetics. Composition, Types, Colors, Structures, Formation, Geology, Occurrence, and Uses of Limestone.
