Abundant rare elements and precious metals are found in the coastal deposits of the east Hainan Island. High-resolution single-channel seismic survey is conducted to effectively define the spatial distribution of the placers in the shallow part of the sea, according to the difference in seismic wave impedance in the sediments consisting of different minerals.

Forty-four surface sediments from a offshore area are analyzed for assessing heavy metals (Cu, Pb, Zn, Cr, Cd, Hg, and As) pollution. High metal values except for As are located in the southern areas which have fine-particle presence. However, high values of the metal As appear at a depth of 15-30 m in the Yazhou Bay.
