Marble is produced in many parts of the world, including Europe, Asia, Africa, and North America. Some of the most famous and productive marble quarries are located in Italy, Greece, Turkey, Spain, China and the United States.

　　Italy is famous for producing some of the finest marble in the world, especially from the Carrara region of Tuscany. Carrara marble has been used for centuries in everything from sculpture to architecture to interior design.

　　Greece is another major marble producer, with high-quality deposits in areas such as Thessaly, Macedonia and the Peloponnese. The ancient Greeks were famous for their extensive use of marble in sculpture and architecture, and Greek marble is still highly regarded today.

　　Turkey is also a major producer of marble, with a rich tradition of marble quarrying and processing dating back thousands of years. Turkish marble is renowned for its quality, variety, and unique patterns and colors.

　　In the United States, marble is found in several states, including Vermont, Colorado, and Georgia. Vermont marble, in particular, is known for its high quality and has been used in many landmark buildings and monuments, including the U.S. Supreme Court and the Lincoln Memorial.

　　Overall, the location and quality of marble deposits can vary widely depending on geological factors such as rock type, deposit age and depth, and the presence of other minerals and impurities. Quarry and processing facilities are usually located close to where the marble is produced, but the finished product may be transported and used in many different places around the world.
