Limestone is a sedimentary rock, formed by inorganic remains, such as shells or skeletons, that have compressed for a very long time. The main element found in limestone is calcium carbonate but it may contain magnesium, iron or manganese as well, which affect the whiteness and hardness.
2017-6-7ensp0183enspLimestone is a sedimentary rock composed of calcium carbonate, plus calcium andor magnesium. It is formed when layers of minerals particularly calcite, fine sediment, and the skeletons and shells of marine organisms undergo lithification. Terrestrially-formed limestone is known as travertine.
Exploring limestones geology, biology, chemistry and uses. Limestone is the rock that fizzes with acid. It has a biogeochemical origin, a rich agricultural history and is literally fizzing with uses and applications.
Most limestones form in shallow, calm, warm marine waters. That type of environment is where organisms capable of forming calcium carbonate shells and skeletons can easily extract the needed ingredients from ocean water.

Chert Uses. In prehistoric times, it was often used as a raw material for the construction of stone tools. When a chert stone is struck against steel, sparks result. This makes it an excellent tool for starting fires, and both flint and common chert were used in various types of fire-starting tools, such as tinderboxes, throughout history.
The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Chert include Arrowheads, Construction aggregate, Cutting tool, Spear points.

The clasts tend to feel smooth to the touch, although the matrix can be either rough or smooth. The hardness and color of the rock is highly variable.
2020-10-3ensp0183enspLimestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO3.1 The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate.
Thus, calcites amp aragonites became primary sources of the skeletons of the living creatures living in the sea and outside the water. Therefore, right from single to multi-cellular animals, Diatoms to Mollusca, and big fishes have contributed a lot to the formation of limestone.

Most limestone is made into crushed stone and used as a construction material, as a crushed stone for road base and railroad ballast, as an aggregate in concrete and is fired in a kiln with crushed shale to make cement.
Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate CaCO3. Most limestone is composed of skeletal fragments of marine organisms such as coral, forams and molluscs. Limestone makes up about 10 of the total volume of all sedimentary rocks.
