The two rivers continuously bring large amount of suspended loads to the seas, about 500×10~6 t (the Changjiang River) and 100×10~6 t (the Huanghe River) per year, which make a great contribution to the sedimentation in the shallow water areas of the展开更多

It is rewarding to prospect the gold abundance in marine sediments through the study of the geology of gold deposits in China. This note reports for the first time the gold abundance in the China Sea sediments. 233 samples including various sediments are selected from the Bohai Sea, the Huanghai Sea, the East China Sea and the South China Sea. They represent a wide distribution range. Among them, 209 are collected from the shelf sea areas where the water depth is less than 200 m. Besides, 24 samples are obtained from Okinawa Trough on the East China Sea continental slope.展开更多
