摘要
随着PL19—3等上第三系大油田的发现，渤海海域晚第三纪沉积环境的研究已势在必行。文中分析了孢粉沉积作用对孢粉化石组合面貌的影响．并根据孢粉沉积作用反演了PLl9—3地区晚第三纪沉积环境。结果表明，馆陶组沉积时期为湖泊三角洲环境，明化镇组下段沉积时期属三角洲一滨浅湖环境，明化镇组上段沉积时期为河流一沼泽环境。
Following several significant oil discoveries, such as PL19 3 oil field, it is needed to study Neogene sedimentary environment in Bohai Bay. In this paper, the effect of palynological sedimentation on sporopollen assemblage is analysed, and Neogene sedimentary environment is inferred from the palynological sedimentation in the PL19 3 area. It can be concluded that the sedimentary environments of Guantao Formation, Lower Minghuazhen Formation and Upper Minghuazhen Formation are lacustrine delta, delta shallow lake and river swamp separately.
