| 摘 要： | 内蒙古自治区呼伦贝尔盟地区海拉尔盆地查干诺尔凹陷扎赉诺尔群自下而上划分为4个孢粉组合。云杉粉Piceaepollenites sp.-单束松粉Abietineaepollenites sp.-三角粒面孢Granulatisporites sp.组合,分布于大磨拐河组一段;罗汉松粉Podocarpidites sp.-双束松粉Pinuspollenites sp.-无突肋纹孢Cicatricosisporites sp.组合,分布于大磨拐河组二段;无突肋纹孢Cicatricosisporites sp.-刺毛孢Pilosisporite sp.-水龙骨单缝孢Polypodiaceaesporites sp.组合,分布于伊敏组一段;有突肋纹孢Appendicisporites sp.-桫椤孢Cyathidites sp.-星粉Astropollis sp.组合,分布于伊敏组二、三段。上述孢粉组合研究证明,大磨拐河组地质时代为早白垩世凡兰吟期—欧特里夫期(Valanginian-Hauterivian),尽管没有出现最原始的被子植物花粉,但也不排除部分进入巴列姆期(Barremian)的可能,伊敏组的地质时代为早白垩世巴列姆期-阿普第期(Barremian-Aptian)。据此认为扎赉诺尔群地质时代为早白垩世凡兰吟期—阿普第期(Valanginian-Aptian)。
