摘要
Located within and outside the Taiwan Strait in the northeastern South China Sea,with the water depths of 3 280 m and 3 378 m separately, two sediment cores HD133 and HD77 are carefully investigated through analysis of grain size,paleontology and calcium carbonate content.The controlling factors for the deep-water sands within these two sediment cores are as the following: temporally,terrigenous sediments are directly delivered into the deep-water settings,forming sand-rich deposits layer 2;spatially,submarine canyons are the conduits for terrigenous gravity flow,making the deposition occur firstly within the canyon.Thus,HD133 is richer in sand than HD77.
