RETROSPECT AND DISCUSSION OF SURVEYS FOR CONSTRUCTION SAND IN CHINA OFFSHORE AREA

In China offshore, the geological survey of marine sediments started in 1950s, and henceforth refined the degree of survey gradually. In 1980s, the solid mineral resources, mainly heavy minerals, were investigated in some parts of China sea areas. From late 1990s, the survey of marine sand for construction commenced rapidly. The marine sand resources greatly support the development of local construction. Meanwhile, owing to the lack of rules and standards related to the exploration and exploitation of marine sand, we discussed the present situation of the lacking and gave some advice to the exploration and exploitation of marine sand.
