Construction marble is a stone which is composed of calcite, dolomite or serpentine which is capable of taking a polish. More generally in construction, specifically the dimension stone trade, the term "marble" is used for any crystalline calcitic rock (and some non-calcitic rocks) useful as building stone.
Besides, why is Marble so important?
The Properties of Marble and Its Uses. Very few rocks have as many uses as marble. It is used for its beauty in architecture and sculpture. It is used because it is an abundant, low-cost commodity in crushed stone prepared for construction projects.
What are the colors of marble?
Color: Marble is usually a light-colored rock. When it is formed from a limestone with very few impurities, it will be white in color. Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color.
