Limestone. 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 a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite. Dolomite is a mineral and a rock-forming mineral that is composed of calcium magnesium carbonate (CaMg (CO3)2). It is named after the French mineralogist Déodat Gratet de Dolomieu, who first described its properties in the late 18th century. Dolomite is often found in sedimentary rock formations and can occur in a variety of colors, ranging ...May 6, 2021 · The clay mineral was dominated by kaolinite, followed by 2:1-type minerals (illite and vermiculite), and a small fraction of mixed-layer minerals.
