These are carbonate sedimentary rocks, compact, fine-grained, formed in marine basins by the accumulation of sediments, the remains of organisms, or by the precipitation of calcium carbonate, etc. They often contain fossil remains such as shells, seaweeds, corals, etc. They often contain fossil remains such as shells, seaweed, corals, etc. It is generally possible to recognize the sedimentation horizons (layers), veins, recemented seams or special seams with jagged patterns known as stylolithic seams.
Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Many limestones are composed of skeletal fragments of marine organisms such as corals or foraminifera. Limestone makes up about 10% of the total volume of all sedimentary rocks.
Limestone is a fairly soft natural stone that is most often recommended for specific applications such as low traffic interior flooring, cladding, stonework and masonry
