Marble is the name of the metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed of calcium carbonate (CaCO 3 ) and usually contains other minerals that might include clay minerals, micas, quartz, pyrite, iron oxide, and graphite .
During metamorphism, the calcite in limestone recrystallizes to form a denser rock with a distinctive crystalline structure. This process not only enhances the hardness and durability of the rock but also often introduces impurities that contribute to the diverse coloration and veining patterns seen in marble.
