Limestone is a sedimentary rock, which means it's formed from layers of sediment being consolidated under great pressure for millions of years. Sometimes, the shells of marine organisms become part of this sedimentation process. These shells are largely responsible for the presence of calcite (calcium

Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz , feldspar , or clay minerals delivered to the site by streams, currents and wave action.

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.

Portland Stone or Portland Stone Formation is a limestone formation from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset, England. The quarries are cut in beds of white-grey limestone separated by chert beds.

Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of 0.5413 g of powdered limestone was measured by suspending the powder in water, adding 10.00 mL of 1.339 M HCl, and heating to dissolve the solid and expel CO2. The excess acid required 39.96 mL of 0.1059 M NaOH for complete titration to a phenolphthalein end point.

As G.H. Dury notes in "An Introduction to Environmental Systems," limestone is a great storage reservoir of calcium carbonate, removing it – if only temporarily – from more active phases of precipitation and dissolution. Fairly resilient in the face of many forms of erosion, limestone is easily excavated by water laced with carbon dioxide.
