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.
In locations where geologic and market stipulations authorize, limestone for collective is mined from underground mines. Despite the fact that mining is more expensive than quarrying, the underground mining of mineral can be a combination of both economical and necessity in some areas of the state.
