Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) in the form of the mineral calcite.
Limestone is a sedimentary rock in the class known as chemical sedimentary rocks. It is composed chiefly of calcite, CaCO 3, and constitutes about 10 percent of all sedimentary rocks. Limestone may form inorganically or by biochemical processes. Coral reefs are examples of limestone produced in the form of the skeletons of the coral invertebrate animals. Calcium-carbonate secreting algae live with the corals and help to cement the structures together. Chalk is another form of biochemically produced limestone. Chalk is a soft, porous rock made up of the skeletal parts of microscopic marine organisms. It produces the white cliffs of Dover, England. Coquina is the name given to limestone in the form of poorly cemented shells and shell fragments. Coral reefs are examples of limestone produced in the form of the skeletons of the coral invertebrate animals. Calcium-carbonate secreting algae live with the corals and help to cement the structures together. In the Beginning. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate), along with minerals. Lime production begins by extracting limestone from quarries and mines Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts What is Limestone. Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago. The second way limestone is formed is when water containing particles of calcium carbonate evaporate, leaving behind the sediment deposit. The water pressure compacts the sediment, creating limestone. The area around the Great Lakes, such as Michigan, Indiana, and Illinois, has a large amount of Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. 71% of all crushed stone produced in the U.S. is either limestone or dolomite. As a source for lime, it is used to make paper, plastics, glass, paint, steel, cement, carpets, used in water treatment and purification plants, in the processing of various foods and household items (including medicines). Type: rock. Description: Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and the chief materials from which aggregate, cement, lime, and building stone are made.
