![]() ![]() The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement.Ī few rocks can produce an extreme reaction with hydrochloric acid. is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. ![]() Oolite limestone is a sub-category of calcarenite. ![]() Some calcarenites contain oolites and if the oolites are present in sufficient quantity, the stone is called oolite limestone. Oolites form today in warm, supersaturated, shallow, highly aggitated marine water.Ĭalcarenite: Calcarenite is composed of sand-sized grains of calcite, usually in the form of tiny fossils, shell fragments and fossil debris. This is a chemical rocks, precipitated from warm, supersaturated marine water. Calcite – CaCO3, formed into small pearl-like spheres, constructed as concentric layers. Dolomitic and chert ooids are most likely the result of the replacement of the original texture in limestone. Ooids are most commonly composed of calcium carbonate (calcite or aragonite), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. What minerals are found in Oolitic limestone?Ĭomposition. Some sedimentary rocks are composed almost entirely of ooids and the calcium carbonate cement that binds them together. Oolitic sediment is found in Great Salt Lake, Utah. Oolitic limestone is found in many parts of the world. Lime also has major applications in the manufacture of glass and in agriculture. Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor. Oolitic limestone is made up of small spheres called ooiliths that are stuck together by lime mud.
