| Abstract: | 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. |
