| Abstract: | Based on field observations and ESR dating of terrace deposits along the upper Minjiang River valley,combined with previously dating ages of the terraces,this paper describes the formation of late Quaternary terraces of the trunk river in the upper reaches of the Minjiang River and its incision history and discusses the response of terrace evolution to the uplift of the Minshan-Longmenshan tectonic belt. |

| Keywords: | Minjiang River river terrace tectonic uplift late Cenozoic ESR dating |
