| 摘 要： | 江苏淮安地区上白垩统含盐地层含有丰富的孢粉化石 ,可划分为 3个孢粉组合 :第 孢粉组合为 Clas-sopollis- Quantonenpollenites组合 ;第 孢粉组合为 Classopollis- Lythraites组合 ,这二个组合的地质时代均为土伦期 ;第 孢粉组合为 Schizaeoisporites- Beaupreaidites组合 ,时代为土伦晚期—桑顿期。当地此时为干旱炎热的亚热带—热带气侯。

| Abstract: | During the Late Cretaceous, there were three assemblages which from salt bearing strata in Huai′an area of Jiangsu, China. Based on the study of these fossil assemblages and evoluted of angiospermous pollen, they may be divided into the Classopollis Quantonenpollenites, Classopollis Lythraites assemblage of Turonian age and Schizaeoisporites Beaupreaidites assmblage of Late Turonian—Santonian age. The three assemblages indicate a dry tropical subtropical climate. |
