郑州市郑东新区地层年代划分探讨

Discussion on stratigraphic age division in Zhengdong new district,Zhengzhou city

利用郑州市郑东新区地震小区划项目一综合地质钻孔资料,通过地层野外描述和孢粉分析两种方法,结合古气候特征,提出了地层年代划分的依据,给出了钻孔深度范围内第四纪早更新世、中更新世、晚更新世和全新世不同时期地层的深度和标志层。对在该地区进行地质工作的人员具有一定的参考意义。

This paper use of Zhengdong new district of Zhengzhou city earthquake plot project a comprehensive geological data,drilling through strata field description and sporopollen analysis of two kinds of methods,combined with the feature of the ancient climate,put forward the formation s division,based on drilling depth is given within the scope of the quaternary early pleistocene,middle pleistocene,the depth of the late pleistocene and holocene strata in different periods and strata. In this paper,for geological work in the region has a certain guiding significance.
