Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the calcite during metamorphism. While marble can appear superficially similar to quartzite, a piece of marble will be able to be scratched by a metal blade, and marble will fizz on contact with dilute hydrochloric acid.

Marble Formation
Marble is a metamorphic rock produced from limestone by pressure and heat in the earth crust due to geological processes. The pressures and temperatures essential to produce this stone generally eliminate any fossils that exist in the initial rock. Due to these forces, the texture of limestone is changed. Impurities in the limestone affect the marble mineral composition.
Marble is available in various colors due to the variety of minerals present in the marble like clay, sand, and silt. It is widely utilized as a building material, in monuments and sculptures, and in numerous other applications. Marbles are suitable for internal and external applications. However, due to modern-day environmental pollution, the polish on marble used for external applications may not be durable.
