| 摘 要： | 对四川名山、邛崃砾石层的砾石成分、砾度和砾向进行统计，分析了该砾石层的物质来源、古流向及阶地特征；并将其与丹棱-思蒙的砾石层进行对比，认为两砾石层是青衣江流域不同地质历史时期的产物；据古流向的分布、砾石层形成年代以及构造运动特征，讨论了青衣江水系总体上由北往南演化变迁的历史过程。

| Abstract: | Correlation of composition, grain size, arrangement direction of gravel bed in Mingshan and Qionglai with those in the Danling-Simeng region indicates that the two gravel beds were formed in different geological periods. Drainage evolution in the Qingyi River valley is discussed on the basis of arrangement direction of gravels, age of the gravel bed and structure. |
