The rare earth elements characteristics of detrital zircons and the U-Pb age of detrital zircons of fine-grained sandstone from Fengping Formation were investigated by the LA-ICP-MS analytical technique. The detrital zircons have a good oscillatory zones and Th/U ratios of most zircons are higher than 0.1, indicating that they are of magmatic origin. The content of REE varies in a large range. The ratios of(La/Yb)_N (0~0.29) and LREE/HREE (0.003×10^-6~0.977×10^-6) show the relative enrichment of HREE. The distribution pattern of rare earth elements in detrital zircons exhibits mainly low content of LREE and high content of HREE as well as Eu negative anomaly and Ce positive anomaly. The result shows that the majority of zircons originated from magmatic source, whereas some other zircons originated from metamorphic activity. The youngest U-Pb age of detrital zircon is 193 Ma, indicating that its diagenetic age is not later than 193 Ma. The data suggest that zircons are mainly composed of 4 age stages, including 2 461~1 743 Ma, 887 Ma, 435 and 422 Ma, 330~193 Ma, respectively, corresponding to the known tectonic-magmatic thermal events (Lüliang Movement, Jinning Movement, Caledonian Movement, Indosinian-Hercynian Movement). The result reveals that the tectonic magmatism in this area is consistent with the tectonic activity in China, and it has the characteristics of continuous development. Through the systematic analysis of the U-Pb dating data of detrital zircons from the sedimentary rock of Fengping Formation and chronology of possible provenances, it is shown that the materials for sedimentation was from surrounding rock mass of Zhongtiao Movement and the Indosinian granite body in southeastern Zhejiang.
