THE STORY OF THE MARBLES
According to the United States Geological Survey, U.S. dimension marble production in 2006 was 46,400 tons valued at $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 20002006 period, compared to 10.5% annually for the 20002005 period. The largest dimension marble application is tile.
Pakistan is one of the largest marble exporters of the world with exports totaling to around a 100,000 tonnes per annum. China is the chief importer of marble, specifically Pakistani marble, with imports amounting to more than 70,000 tonnes in a single calendar year.
