The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。
