Abstract:In this study, REE concentrations of Shanxi-Taiyuan Formation shale, eastern uplift of Liaohe Basin were tested by means of ICP-MS. The content of ∑REE、∑LREE、∑HREE are higher than that of the NASC, UCC, PAAS. The characteristics of chemical parameters and REE distribution curve shows that LREE are abundant, with moderately negative anomaly of Eu, weak Ce anomaly, very obviously negative anomaly of Tm, and similarly provenances according to the paralleled curves of samples.The characteristics of Ceanom and Eu reflect the oxidizing-reducing transition in sedimentary water mediums environment and humid paleoclimate. The ratio of (La/Yb)N and distribution patterns suggest low sedimentary rate with still changing trend from low to high from bottom, far away from provenance. According to the source rocks and tectonic setting discrimination diagrams,the provenances of shanxi-taiyuan Formation were mainly mixture of sedimentary rock and basalt, with the tectonic setting of continental island arc cutting magmatic rocks.
