Limestone Features
Limestone is a sedimentary rock which is formed underwater. Some limestone consists mainly of coral or the shells of other small marine creatures. Limestone may also be precipitated from seawater. Limestone is a permeable rock. This means that water can enter limestone through pores, joints or cracks in the rock.

How Lime is Made
Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate), along with minerals. Lime production begins by extracting limestone from quarries and mines. Sizing . . . Limestone enters a primary crusher to break the rock.

How does weathering affect limestone?
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve.
