What is the difference between Limestone and Marble?

Limestone is an example of sedimentary rock and is formed through the accumulation of materials such as sand, mud, shells in oceans. It can also form through the precipitation of calcium carbonate from ocean water. Marble, on the other hand, is a metamorphic rock and is formed when limestone recrystallizes.

Both cannot be differentiated in terms of color because they come in different colors. However, it is important to know that limestone has more uses compared to marble; while the former is used in different areas, the latter is used mainly for sculptural works.

While the formation of marble is usually due to the action of pressure and heat on limestone, the action of pressure and heat is not part of the formation of limestone. Since limestone is porous, it is soluble in water, whereas the solubility of marble in water is not in the same degree as that of limestone.

Limestone and marble are two types of rocks. Limestone is a sedimentary rock. It is formed from shells, sand, and muds. After they are formed, they are taken to lakes and ponds. From there, they transform into sedimentary rocks. Limestones can be a number of colors including yellow, gray, and blue and can vary in size. On the contrary, marble is formed when limestone is recrystallized.

This happens when rocks are formed and caused by the heat of limestone. Compared to limestones, marbles are metamorphic rocks. They also come in many different colors and are used in sculptures and materials.

First of all, let us discuss limestone. Limestone is a form or example of sedimentary rock, and it is formed when shells, mud, and sand are deposited in lakes and ocean, and then develop into a sedimentary rock. Since its constituents are of fossilized particles, you will discover that it is porous and also soluble in water.

A typical limestone is composed of sand, silt, clay, and silica. It is of several colors, and may also be elastic, massive, crystalline or granular. It is a bit expensive material, and very liable for construction. On the other hand, marble is also a rock that Is formed when there is a recrystallization of limestone during mountain building process.

This occurs typically during the formation of rocks, due to the heating and squeezing of limestone that causes the rock grains to recrystallize. Marbles is a form of metamorphic rock, and it is usually used in sculptures and as building material. It is also a material of many colors.
