摘要
滨海区位于华北地台与扬子准地台的交界处,在三年的找煤工作中发现了完整的石炭纪地层。其中早石炭世地层沉积厚度大、发育全,动植物化石亦较丰富。笔者对该区下石炭统进行了较详细的划分,并与宁镇区进行了对比,提出了对比上的几条意见。
The Lower Carboniferous series in the Jiangsu Province mainly distributes in the Ning-Zheng area which has been deeply researched.Because of the incomple- tion,there still remains many problems to be solved,e.g.the time classification and contact relations of the Gaolishan and Jinling Formations. Through coal exploration in the Binhai county,a complete Lower Carboniferous series has been found which is very useful to solve the problems remamed.in the south regin.The paper also describes the complete stragraphic section and set up two new formations,i.e.Xingang and Laokan formations.According to the corr- elations on the Lower Carboniferous series in different places,the Hezhou,Xingang and Gaolishan formations were deposited in Datang Stage and Jinling,Laokan for- mations were deposited in the Yanguan Stage.Laokan and Xingang formations are lacuna in Ning-Zheng area.Therefore,Xingang formation can be correlated with the Ceshui formation and Gaolishan formation is just as the Shichengzi member.
