Limestone vs. Marble: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 4, 2024
Limestone is a sedimentary rock composed mainly of calcite, while marble is a metamorphic rock formed by the metamorphism of limestone, known for its crystalline structure and used in sculpture and architecture.

Key Differences

Limestone is a sedimentary rock, formed primarily from the mineral calcite, often derived from the accumulation of shell, coral, algal, and fecal debris. Marble, however, is a metamorphic rock that originates as limestone and undergoes metamorphism under high pressure and temperature, leading to a more crystalline structure.

The texture of limestone is typically granular and can include fossils and layers, indicative of its sedimentary origin. Marble is characterized by its medium to coarse grains and uniform texture, lacking the layering found in limestone, a result of its metamorphic transformation.

Limestone is generally softer and more porous than marble, making it less durable for certain applications. Marble, due to its metamorphic nature, is harder and less porous, making it more suitable for fine sculpture and building materials.

Limestone often appears in a spectrum of natural, earthy colors due to impurities like clay, sand, and organic remains. Marble, known for its elegance, typically showcases a range of colors with veins running through it, created by mineral impurities like silt, sand, and iron oxides.

In terms of applications, limestone is widely used in construction, aggregate, and agricultural lime. Marble is preferred in art, architecture, and as a building material for its aesthetic appeal and durability.
