摘　　要：辽宁沈阳西南郊苏家屯以南，以永乐为起点，呈宽约２７ｋｍ的条带状，向南西方向延伸着一片第三纪含煤地层，其时代曾有古新世～始新世、古新世～渐新世、晚始新世～早渐新世之争。通过对其所含孢粉组合的再研究，证实其层位相当于抚顺煤田的古城子组－西露天组，时代应为始新世。Abstract There is a banded tertiarv coal～bearing strata distributed along east-west directionat south of Sujiatun in the southwest part of Shenyang, Liaoning Province,its startingpoint being at Yongle,its width 27 km.Its geological age is considered as paleocene-eocene or paleocene-Oligocene or late eocene-early oligocene. This Paper confirms thatits stratohorizon is equal to Guchengzi-Xilutian formation of Fushun Coal Field by rein-restigating the sporopollen assemblages in it,its geological age should be eocene.SUBJECT TERMS:Yongle,Liaoning Province. tertiary,Eocene, geological age,stra-ta
