| Abstract: | Based on the projects of "Comprehensive Geological Survey in Ninghe County,Tianjin","Comprehensive Geological Survey in Jinghai County,Tianjin" and "Qilihai Geological Park",a few drilling holes are setted out in this area,take ZK01-ZK09 holes,BHN10 hole and BJM18 hole,SQ01-SQ29 holes and TK01-TK09 holes for example,the stratotype section of the Holocence epoch strata in the west coast of Bohai Gulf are segmented and divided into groups.According to stratigraphic code and grouping requirement,combing the data of lithologic stratigraphy,chronostratigraphy,chemistry strate and biological assemblages strate,the author divided the stratotype section of the holocence epoch strata into three groups:Duliuzhen group,Dahuangwa group,Xizhaizhuang group.The segmentation boundary between upper Holocence Duliuzhen group profiles and middle Holocence Dahuangwa group profiles are from 5.10 m to 5.25 m; the segmentation boundary between middle Holocence Dahuangwa group profiles and lower Holocence Xizhaizhuang group profiles are from 13.80 m to 14.10 m; the segementation boundary between lower Holocence Xizhaizhuang group profiles and lower Pleistoncene Tanggu group profiles are from 18.48 m to 18.70 m.The division of Ⅰ～Ⅴ cold climate section is accordance with the chemical environment related indexes,for example,the content of CaCO3,pollen paleotemperature and the retio of Rb/Sr.The division of Ⅰ·～Ⅴ· oxidation-reduction zone is accordance with the comprehensive analysis for the concentration curve of Corg/P2O5、Fe2+/Fe3+. |
