| Coral reefs belong to biominerals and their composition is not fixed, so changes in coral reefs composition often have certain indicative effect on local ecology and minerals, and their element analysis plays an important role in the ecological restoration of coral reefs and seabed prospecting. In this paper, samples were collected from the South China Sea near an island reef. The energy dispersive X-ray fluorescence spectroscopy was used to analyze the coral reef samples. It was determined that the inorganic components include Al, Fe, Sr and other elements besides Ca. The calcium content accounts for about 96%, followed by the content of Sr accounts for about 2%, S accounts for about 0.4%, Al and Fe account for about 0.1% each, and the rest are other elements. At the same time, the analysis of sample elements take from different regions shows that one of the samples contains a large amount of Co. This experiment has practical significance for the comprehensive understanding of the composition of coral reefs in the South China Sea and the indication of mineral deposits in the South China Sea. |
