The main difference between granite and marble is that granite is a highly dense material composed deep inside the earth?s core while marble is formed from sediments under the seabed. Both solidify into stone after millions of years but the mineral composition of the two stones makes marble and granite react differently to various chemicals and household cleaners See similar questions...

Although both are stones and both are quarried from the earth, granite and marble are very different from each other. Granite is one of the oldest, most durable and most respected of building materials. Traditionally, it is the material chosen by both architects and engineers when permanence, enduring color and texture, and complete freedom from deterioration and maintenance are prime requirements.

Limestone and Marble show subtle veining and movement. They are sedimentary rocks composed primarily of calcium carbonate and so are sensitive to acids. Marble derives from the Latin “marmor” which means “to shine,” so marbles are hard limestone's that accept a polish well. Granites are harder rocks of volcanic origin and are not acid sensitive.

Granite is formed deep in the earth's mantle at extremely high temperatures. It is a very hard, resistant stone made of crystallized minerals. Marble starts out as sediment - animal skeletons and shells, plant matter, silt - at the bottom of bodies of water. After millions of years this solidifies into stone. See similar questions...

The composition of granite and marble is very different. Granite is an igneous rock that was once a molten mass called magma. Marble is created by a concentration of bones and shells of sea creatures that build up a deposit of lime. Therefore, marble is not nearly as hard as granite and will erode over the years. Granite is the preferred material to use for memorials because of its durability. See similar questions...
