| Abstract: | Paleogene strata in South Jiangsu are mostly buried under thick overcast. Being lack of perfect outcrops, the strata can only be investigated by a vast of drilling hole data. Then, there exist many different statements about the strata. The thickness of well developed Paleogene monorhythmite is over 2 092m in Zhixiqiao basin. Associated volcanic activities, different detrital rocks constitute Taizhou, Funing Formations from early, middle and late Paleocene. During Eocene and Oligocene, developed ribbon sediments and reddish detrital rocks respectively,the thickness of strata were decreased gradually from the center of the basin to the margin. Through the comprehensive analysis of sporopollen data in the drilling hole of Zhixiqiao basin, the stratigraphic sequence and time classification of the strata are determined to clarify the paleoclimate and paleoenvironment during Paleogene System. |
