摘要
基于岷江上游干流阶地地貌的野外观察和阶地沉积物的ESR年代测定,结合前人阶地测年数据,阐述了岷江上游干流晚第四纪阶地的形成过程和河谷下切历史,探讨了阶地演化对岷山和龙门山构造带隆升的响应过程。
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.
