How does granite compare to marble in terms of resistance to decay?

Granite and marble are two of the most popular natural stones used in construction and design. When it comes to resistance to decay, granite generally outperforms marble. Granite is an igneous rock, formed under extreme heat and pressure, which makes it highly durable and resistant to weathering, chemical erosion, and physical wear. Its dense structure and low porosity contribute to its ability to withstand decay over time.

Marble, on the other hand, is a metamorphic rock composed primarily of calcite. While it is elegant and visually appealing, marble is more susceptible to decay due to its higher porosity and softer composition. It is prone to etching from acidic substances and can be damaged by prolonged exposure to moisture and environmental pollutants.

In summary, granite is the more decay-resistant option, making it ideal for high-traffic areas and outdoor applications. Marble, while beautiful, requires more maintenance and is better suited for indoor use where it is less exposed to harsh conditions.
