| Abstract: | Having analysed the tectonic history and the characteristics of the strata (Cenozoic) of Emei Platform, the author finds that the former Fen River on Emei Platform has changed its flow direction several times since Pliocene epoch. Owing to the movements of Zhijin Mountain and Emei Platform, the river stopped flowing through Emei Platform in the middle Pleistocene epoch. From that time on, the river has flowed west through Xinjang Jishan and Hejin into Yellow River. |
