Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word "granite" comes from the Latin "granum", a grain, in reference to the coarse-grained structure of such a holocrystalline rock. Strictly speaking, granite is an igneous rock with between 20% and 60% quartz by volume, and at least 35% of the total feldspar consisting of alkali feldspar, although commonly the term "granite" is used to refer to a wider range of coarse-grained igneous rocks containing quartz
Rock of Ages Corporation natural stone producer, announced the acquisition of Swenson Granite and Rock of Ages Corporation to become the largest producer of marble and granite in North America. This also includes the Canadian division of Rock of Ages Corporation, located in Stanstead, Quebec, along the Vermont and Quebec border. ROAC maintains the world's largest "deep hole" granite quarry. The quarry is called the "E. L. Smith Quarry", and the Devonian Barre Granite is mined there. Granite was originally quarried using primitive techniques which implemented hand saws and explosive charges to blast away the "benches" of the quarry. Modern techniques have evolved to
