摘要
选用14口井的孢粉化石资料，将鉴定出的50个属，110个种概括为4个组合，根据孢粉组合特征提出了渤海地区中侏罗世和早白垩世地质时代最新划分意见，为该区中生界划分为与对比提供了较可靠的孢粉学依据。
In this study,the sporo-pollen fossils from 14 wells are used. Through sampling and analysing,the total about 50 genera and 110 species are collected and grouped into 4 assemblages. Based on the characteristics of sporo-pollen,the new proposal for geological division of middle Jurassic and early Cretaceous in Bo-hai region is recommended, which provides the reliable sporo-pollen data for stratigraphic division and correlation.
