Linxia is a district in Gansu Province,locates in the north-east edge of the Tibetan Plateau.Huge thick of Cenozoic red stratum over last 4～29 Ma was reported there,providing valuable geological record to recognize the Ppateau uplifting process and climatic evolution during Cenozoic.The results show that: both horizontal and titled “Zebra Layers” are all likely to be the original deposition,no evidence to support the titled bedding was due to the tectonic movement made the horizontal layers to be titled.Today Maomao Ditch,Jiaozi Ditch and Mao Ditch,are all first level of branch of Xia River system,while Xia River is the first level of branch of Yellow River,indicating very likely that the Yellow River for this certain part may also have formed at least 13 Ma ago according to paleomagnetic dating.
