| Abstract: | Based on the field investigation and drill log and experimental results as well as other data, several type sections are described in this paper. The principles of stratigraphic division and correlation are discussed also. Holocene series in Zhengzhou may be divided into three formations: (1) Lower Holocene Dali (11000-7500 years), (2) Middle Holocene Dahe-cun (7500-2500 years) and (3) Upper Holocene Putian (2500-present). |
