Marble is what type of rock?

The metamorphic rock marble is formed when limestone is subjected to intense heat and pressure deep within the Earth's crust. During this process, the minerals are recrystallized, giving marble its characteristic veining and smooth texture. Mostly composed of calcite (CaCO3), marble is prized for its elegance, making it a popular choice for flooring, countertops, and sculpture. As a result of its durability and natural beauty, it is a timeless material in architecture and design.
