风化、搬运,沉积和成岩作用被看作是沉积旋回的几个主要阶段,这些阶段可能对沉积物中稀土元素(REE)的分布和丰度产生不同的影响。为估价成岩作用对REE分布的影响,我们于本文中提出了墨西哥湾海岸区埋藏沉积物的全样和不同粒级中REE的分析结果。分析样品采自美国路易斯安那州南帕斯地区一个深井中的一组侧壁上的软泥和粉砂质软泥岩心。 Weathering, handling, sedimentation and diagenesis are considered as the major phases of sedimentary cycles that may have different effects on the distribution and abundance of REEs in sediments. In order to estimate the effect of diagenesis on REE distribution, we present the full sample of burial sediments in the Gulf Coast and the results of REE analysis in different fractions. Analytical samples were collected from a series of side-walls of slime and silty soft clay cores in a deep well in South Paas, Louisiana, USA.
