| 摘 要： | 西藏北部丁固-加措地区,分布一套零星出露的、固结—半固结状态的砂砾岩层,在综合研究其岩石组合、沉积特征、地质时代、区域地质特征的基础上,将其厘定为一个非正式岩石地层单位——高台阶砾石层,该砾石层对研究区内第四系地质演化具有重要意义。

| Abstract: | In the Dinggu-Jiacuo area of north Tibet, there is some exposed, solidified and semi-solidified gravel distributed, on the basis of studying the rock composition, sedimentary feature, geologic era and regional geologic characters, it is determined to be a informal stratigraphic unit:gravel layer of high stage, it will be important for Quaternary study in the target area. |
