| Abstract: | Geophysics, Chinese Academy of Sciences, Beijing 100101, China)Geotectonically, the Youjiang sedimentary basin was referred as Youjiang Indosinian folded belt. The characteristics of turbidite clastics and heavy mineral compositions and palaeocurrent direction show that the Middle Triassic turbidites accumulated in the basin are derived from surrounding ancient lands including Yuebei, Jiangnan, and Yunkai. The REE characteristics of turbidites are similar to those of active continental margin and continental island arc. The overall shape of the average REE pattern is also similar to those of active continental margin |
