Limestone | Minerals Education Coalition

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.
