Difference Between Limestone and Marble

Limestone is a rock that is formed when mud, sand, and shells are deposited in oceans and lakes and develop into a sedimentary rock. Since it is made up of fossilized particles, it is porous and is soluble in water. It is composed of silica, clay, silt, and sand. It also has many colors and may be crystalline, clastic, granular, or massive.

What happens when acid reacts with limestone? Questions ...

Answer. Limestone is mostly made up of the mineral calcium carbonate CaCO3 . This is not very soluble, so rocks don& 39;t dissolve very quickly. But if you add an acid, you add hydrogen ions H , which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.

Limestone Vs. Marble Hunker

Limestone, a sedimentary rock, forms when shells, sand and fossils solidify over millions of years. When limestone experiences high heat and pressure beneath the earth, it may transform into marble, a metamorphic rock. As the rock is subject to natural heat and pressure, it recrystallizes, growing harder and denser over time. Mineral deposits add color and give marble its distinctive veining and grain.

However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid.

Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble.
