Based on the oceanic geological investigation references obtained from the regional geological surveying and mapping of China Sea (“Shantoufu, F 50” 1∶1 000 000) and on the data (“Marine Engineering Geological Investigation Project in the Pearl River Mouth basin in the South China Sea” 1∶200 000), the authors elaborate the grain size composition, mineral composition, mineral features and distribution pattern of the surface sediments in the sea at 114°-120°E and 20°-24°N. Moreover, the analysis of the regional solid state mineral resources in the coast of Fujian, Guangdong and the west of Taiwan, shows that the main resources include littoral/neritic placers, littoral/neritic sandy gravel and ferromanganese nodule (crust). In addition, the future focus should be on the placers and sandy gravels in this littoral area.展开更多
