Marble is a metamorphic stone.  Marble is composed primarily of calcium carbonate or calcite.  Marble is formed differently than granite.  It has never flowed like granite, but is basically pressed together.  The veins in marble are minerals and other impurities which have filled in the fissures or cracks.  Marble is softer and more porous than granite.  Marble is a good choice in bathrooms.  When polished and sealed it repels soap scum.  It is easy to clean and adds elegance and beauty in any application..
