Lime Stone
Limestone rocks contain more than 50% calcium carbonate mineral. Extensive karst forms in limestone areas as the minerals react chemically with dissolved carbon dioxide and organic acids. 

Although calcite is usually the most abundant mineral, other common minerals include aragonite, dolomite and magnesite (magnesium carbonate). Limestone is considered as a carbonate rock. In short Lime stone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust.

Uses: Limestone is use in construction industry (dimension stone) and the important materials from which aggregate, cement, lime, and building stone are made. As a source for lime, it is used to make paper, plastics, glass, paint, steel, cement. Used in water treatment and purification plants, in the processing of various foods, household items and in medicines.
