Marble resources are very abundant in the world, but they are distributed unevenly or insufficient in commodity. The main marble producers in the world are Italy, China, Spain, Portugal, Greece, Turkey, the Philippine, France, Brazil, the United States, India, Austria, Russia and Japan. Italy has boundiful marble resources and is the most important marble source and producer in the world.
As marble is a staple mineral commodity and in most cases it is explored for in local places according to the demands, the statistics of the world's marble resources and reserves are lacking. From the present explored marble reserves and state of development, China is one of the few countries that have abundant marble reserves in the world.
Marble reserves of China
Marble resources are abundant in China. It is of all patterns and varieties and distributed throughout China. Up to the end of 1997, there were 167 marble occurrences, with retained reserves of 1,089 million m3, of which categories A+B+C reserves are 426 million m3. The reserves of marble are given in Table 4.25.1.

For a long time China has not regarded marble as a sole resource that is mined, and limited exploration has been conducted. In the past 10-odd years, with increased demands on the markets and development of geological exploration, reserves have increased rapidly. However, considerable amounts of resources have not been subjected to geological exploration, so no explored reserves are available; and moreover, some unexplored areas have been developed by the local people. According to the Report on '96 Mineral Resources of China, it is estimated that the total resources of marble in China may reach 20 billion m3. The present explored reserves only account for 5% of the total resources.
China inputs more geological exploration work in economically developed eastern China and coastal areas. The level of previous exploration was low in these areas, but as these areas are generally endowed with good mineralization conditions, so long as appropriate exploration work is input according to demand of the market, there will be still great potential for the increase of retained granite reserves.
