MINERAL ASSEMBLAGES AND THEIR DISTRIBUTION PATTERN IN THE SEDIMENTS FROM THE NORTH CONTINENTAL SHELF OF THE SOUTH CHINA SEA AND THE BEIBU GULF |
| |
| Abstract: | The results of our study show that there are a total of 56 minerals in the sediment samples analyzed. The area investigated may be divided into 3 mineral provinces on the basis of the heavy and light minerals. 1. The north mineral province of the South China Sea is characterized by the higher content of the schistose mineral and dolomite supplied by the Zhujiang River. 2. The Hainan Island mineral province contains a significant amount of ilmenite, zircon and tourmaline contributed by the marine erosion of Hainan Island. 3. The Beibu gulf mineral province can be recognized by its higher content of sillimanite and tourmaline brought by the Hong River and other rivers. |
