| 摘 要： | 松辽盆地东南隆起区深部地层十分发育,含丰富的孢粉化石,所建立的4个孢粉组合,为地层划分对比和时代确定提供了生物地层学依据。火石岭组相当于晚侏罗世,沙河子组为早白垩世凡兰吟期至戈特里夫期,营城组为早白垩世巴列姆期,十屋组为早白垩世阿普第期。

| Abstract: | The deep layers of the upwelling area, southeastern part of the Songliao Basin are well developed, which contain rich sporomorphs.A Biostratigraphic evidence established for correlation of stratigraphic division and the age is provided by four aporopollen assemblages. The Huoshiling Formation corres ponds to later Jurassic, the Shahezi Formation is referred to the early Cretaceous Valanginian-Hauterivian Stage, Yingcheng Formation is referred to the early Cretaceous Barremian Stage and the Siwu Formation is referred to the early Cretaceous Aptian Stage. |
