摘要
简述了研究区不同实测剖面的特征及其地形地貌特点,并通过对不同成因地层各层位的光释光(OSL)、电子自旋共振(ESR)和14C测年,确立了早更新世、中更新、晚更新世地层系统,从而对研究区第四系地层系统进行了较精确的划分,为晚新生代构造隆升、构造地貌以及环境研究提供了重要信息.
This paper formulates the characteristics of several field survey profiles and the topography and landforms. Dating the strata by OSL, ESR and ^(14)C, the authors establish a stratigraphic system of Early Pleistocene, Middle Pleistocene and Late Pleistocene, which will make it possible for us to classify the Quaternary stratum system accurately in the study area. This may provide important information for the research on Late Cenozoic tectonic uplifting, tectonic landforms and environment.
