在绝大部分研究海洋沉积物稀土元素地球化学的工作中 ,作为研究对象的是太平洋底质。我们认为其原因是太平洋中海洋成岩作用类型表现较明显。对此 ,巨大的海洋面积起了促进作用 ,因此海洋中物质分异程度较大 ,远洋环境和沉积物类型的多样性也较突出。大西洋沉积物稀土元素的行 In most of the work on the REE geochemistry of marine sediments, the Pacific Ocean substrate was studied. We think that the reason is that the type of marine diagenesis in the Pacific Ocean is more obvious. In this regard, a huge ocean area has played a catalytic role, so the degree of material differentiation in the ocean is large, and the diversity of oceanic environment and sediment types is also prominent.
