摘　　要：通过对山东聊城许营地区 2 0 、 1 4钻孔石炭 -二叠系与第四系 (平原组 )之间新近纪地层中孢粉化石和介形虫化石研究 ,建立了一个 Magnastriatites- Ulmipollenites- L iquidambarpollenites孢粉组合和一个 L imno-cythere gudaoensis- Cyprinotus(H eterocypris) formalis- Candona planus介形虫组合。上述孢粉组合和介形虫组合经与山东北部、渤海海域、江苏北部、陕西渭河盆地、松辽盆地、东海陆架盆地龙井构造带等地新近纪地层对比 。Recently the authors analyzed samples from drillholes Ⅱ 20 and Ⅶ 14 in Neogene strata between the Permian and Quaternary in Liaocheng, Shandong Province. A large number of sporo-pollens and ostracods fossils were discovered. A palynology assemblage of Magnastriatites-Ulmipollenites-Liquidambarpollenites and an ostracod assemblage of Cyprinotus-Candona-Candoniella were found. Through a comparison with the strata of northern Shandong, the Bohai Sea region, northern Jiangsu, the Weihe basin of Shanxi, the Songliao basin, the Longjing structural zone in the East China Sea Shelf Basin etc., they should be ascribed to the middle Middle Miocene in age.
