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.

Dolomite | NZ's Finest Magnesium Fertiliser

Dolomite will do this just as readily as ordinary limestone and a tonne supplies about 240kg of Ca and 100kg of Mg. Where soils are acid and hypomagnesaemia a problem, dolomite should be considered as a cure for both. Where dolomite is as cheap as ordinary limestone there is no question that dolomite is to be preferred.
