摘　　要：首次在松辽盆地北部黑富地1井上二叠统四站板岩组采获孢粉化石,称为Protohaploxypinus fertilis-Piceaepollenites opimus-Alisporites communis组合,该组合裸子植物花粉占绝对优势地位,蕨类植物孢子含量低且属种贫乏.裸子植物花粉以无肋双囊粉含量最多,其次为具肋双囊粉,单气囊花粉含量较少,可与新疆北部准噶尔盆地、塔里木盆地晚二叠世和大兴安岭地区林西组孢粉组合对比,时代为晚二叠世.孢粉化石赋存井段岩性组合特征与林西组相似,因此松辽盆地西部大兴安岭地区的林西组可引入松辽盆地内,原四站板岩组改称林西组.The sporopollen assemblage of Protohaploxypinus-Piceaepollenites Opimus-Alisporites Communis,collected for the first time in the Upper Permian Sizhanbanyan Formation from HFD1 well in northern Songliao Basin,is dominated by the pollen of gymnosperms,while pteridophytes are characterized by low spore content and poor species.Of the pollen contents of gymnosperms,non-striate bisaccate pollen is the highest,followed by striate bisaccate pollen,with less monosaccate pollen,which are comparable with the sporopollen assemblages of the Late Permian in Junggar and Tarim basins in Xinjiang and the Linxi Formation in Daxinganling Mountains,indicating the age is also Late Permian.As the lithologic characteristics of the strata with sporopollen assemblages are similar to those of Linxi Formation,the Linxi Formation of Daxinganling Mountains on the west of Songliao Basin can be introduced to replace the former Sizhanbanyan Formation.
