How does the density of granite compare to marble?

Granite and marble are two of the most popular natural stones used in construction and design, but they differ significantly in density. Granite is generally denser than marble, with an average density ranging from 2.63 to 2.75 grams per cubic centimeter (g/cm³). In contrast, marble has a lower density, typically between 2.5 and 2.7 g/cm³. This difference in density is due to their distinct mineral compositions and formation processes. Granite, an igneous rock, is formed from the slow crystallization of magma, resulting in a tightly packed structure. Marble, a metamorphic rock, originates from limestone and undergoes recrystallization, which creates a less dense and more porous texture. The higher density of granite makes it more durable and resistant to wear, making it ideal for high-traffic areas like countertops and flooring. Marble, while less dense, is prized for its aesthetic appeal and is often used in decorative applications. Understanding these differences helps in selecting the right stone for specific projects, balancing durability, functionality, and visual appeal.
