Xiaogan belongs to the Yun-meng Lakes in ancient times. That is why its geology is developed so well and its underground minerals are so rich. Mineral products discovered by now, being 23 different types, can be divided into 7 kinds, among which there are 11 high quality minerals and cream, salt and phosphor are being hailed as the “three treasures of Xiaogan”. Geological reserves of plaster in Yingcheng are 429 million ton. Plaster, especially fiber plaster, has the top quality in Asia and has storage of 880 million ton, which is 92.3% of the provincial storage and 58.7% of the national storage. Rock salt in Yunmeng and Yingcheng has a great content of sodium chloride. Geological reserves of it are 280 billion ton, among which there are 50 billion ton which could be used in industry. In 1988, it was detected that there were rock salt resources in Ma River of Hanchuan which has an industrial reserves of 94 million ton. Geological reserves of phosphorite are 172 million ton and are easy for exploitation. With most rock ores concentrated together, sodium sulfate storage in Yunmeng is 54 million. Precious metal minerals in Xiaogan which is easy for exploitation also include rare earth, golden, silver, copper and nickel, among which the storage of heavy rare earth is 31000 ton, taking up 100% of the provincial storage. Geological storage of the nickel in Dawu is 265600 ton, taking up 100% of the provincial storage, too. Up until now, except golden, silver and copper, which have been exploited in small scale, all the minerals remain untouched. Besides, there are abundant storage of barite (4.67 million ton), marble (2 million cubic meters), granite (15.36 million cubic meters), micarex (140.7 ton, taking up 81% of the provincial storage) and serpentinite (167 million ton, taking up 100% of the provincial storage) and mineral water and so on.
