What is a Limestone? - Definition from Corrosionpedia
Limestone is formed partly by chemical processes and partly biological process. Most limestone is composed of skeletal fragments of marine organisms such as coral. Pure limestone is white or almost white but because of impurities such as clay sand organic remains iron oxide and other materials many limestones exhibit different colors especially on weathered surfaces.
