摘要
本文对四川江油龙潭子下-中三叠统界线剖面的稀土元素含量作了测试和分析。结果表明,界线层内有不同程度的稀土元素富集,其含量较上覆、下伏地层为高,且显示出Ce、Eu的负异常。
Contents of REE in the Lower-Middle Triassic boundary section in Longtanzi,Jiangyou, Sichuan were measured and analysed. REE got enrichments in the boundary bed, which has relatively high contents than those in its overlying and underlying beds,showing the negative anomalies of Ce and Eu.
