| 摘 要： | 在全面系统分析、整理第四纪地层资料基础上，以岩石地层为基础，以古地磁、１４Ｃ、热释光测年资料为依据，以化石资料为参考，对更新统及全新统进行了岩石地层、磁性地层单位的对比和划分；重新厘定了一些地层单位的名称和含义；统一了各地层区的地层系统；建立并进一步完善了甘肃第四纪地层层序。确定了兰州、陇西及陇东地区黄土的开始沉积时间。对甘肃第四系的动物群及新构造运动的特征进行了论述。

| Abstract: | Based on lithostratigraphy,in accordance with data of magnetostratigraphy, 14 C and thermoluminescent dating,refered to fossil data,the Holocene and Pleistocene lithostratigraphic and magnetostratigraphic units were divided and correlated.The name and meaning of some stratigraphic units were newly collated and stipulated. The stratigraphic serirses in some stratigraphic province were unifed.The Quaternary stratigraphic sequence in Gansu Province were established and were further perfected.Loess beginning sedimentary time in Lanzhou,Longdong and Longxi areas of Gansu were determined.The characteristics of faunas and neotectonic movement in Gansu Quaternary were discussed. |
