| 摘 要： | 阿尔金山北麓晚新生代沉积物比较敏感地记录了阿尔金山构造活动的历史.通过若羌-米兰剖面晚新生代沉积特征表明中新世晚期以来该区沉积环境经历了从湖相到扇三角洲,最后至洪积扇和河流相沉积演化.依据沉积物岩性、沉积物粒度、沉积环境、古流向等的变化以及地层接触关系分析,揭示了阿尔金山晚新生代以来经历的晚中新世-早上新世,晚上新世和中更新世三次重大构造活动的历史.

| Abstract: | The sediments of the late Cenozoic in the northern margin of Altun Tagh mountain have sensitively recorded the tectonic movement of the mountain.The characteristics of sedimentary evolution of Cenozoic straitigraphy of Ruoqiang-Milan section revealed that the tectonic movement of Altun Tagh mountain has experienced three phases in Cenozoic:late Miocene,late Pliocene and middle Pleistocene. |
