Abstract

Abstract

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. Seismic attribute clustering/classification methods are used to put seismic facies into sedimentary facies so as to better understand the origin of the deposits. Then, in combination of drilling results, the spatial distribution of sand deposits is defined for resource assessment.
