| 摘 要： | 通过对苏北盆地盐城组样品进行分析观察,对孢粉组合、介形类、古脊椎动物化石及物质成分等进行研究,指出盐城组沉积期全盆地均为陆上洪水环境。盐一段沉积期山地发育,为湿润多雨的北亚热带气候;盐二段沉积期发育广阔的冲积平原,为偏温湿的北北亚热带气候。对探讨苏北盆地上第三系盐城组沉积环境有一定意义。

| Abstract: | Through analysis and observation of core samples of Yancheng formation in Subei basin,It was studied on sporo-pollen assemblages,ostracods,vertebrate,substance components,etc.in the formation.Finally,it was pointed out that the whole basin was overland-flood environment during depositional stage of Yancheng formation.In Yan-1 depositional stage,there were developed-mountains and northern subtropic climate with rainy and humid.In Yan-2 depositional stage,there was developed-wide alluvial plain and north-north subtropic climate with slight warmer and humid.This is import to study on the depositional environment of Yancheng formation in Subei Basin. |
