MorePure limestones are white or almost white.Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces.Limestone may be crystalline, clastic, granular,.
MoreLimestone is a sedimentary rock mostly composed of the mineral calcite, a carbonate material, and contains variable amounts of silica from flint and chert along with clay, sand, and silt.The calcite in limestone is primarily made up of marine organisms whose shells secrete and settle on the ocean floor.
MoreLimestones are very common in architecture, especially in europe and north america.Many landmarks across the world, including the great pyramid and its associated complex in giza, egypt, were made of.
