摘要
充分应用前人对二连盆地各个坳陷的中新生代孢粉资料的统计结果,同时对比参照了相邻的松辽盆地和鄂尔多斯盆地的对应时代地层的孢粉资料。根据各孢粉化石母体植物生态环境的不同,将其分类统计,进而得出该时期的古气候特征。再通过古气候的岩相和矿产标志,定性的恢复了二连盆地的古气候。再将之与孢粉定量重建的古气候作对比。综合地得出了二连盆地中新生代古气候的演化规律。
On the base of the classification statistic of Mesozoic and Cenozoic pollen and spore data in the different depression of Erlian basin, the paleoclimate was reconstructed depending on the different parent vegetation eco-environment of the pollen and spore. Meanwhile, according to climatic indicator of Erlian basin＇s lithofacies and continental special deposits, the paleoclimate was reconstructed by the qualitative analysis. Then paleocliamite evolution rule of Erlian basin from Mesozoic to Cenozoic can be concluded by the contrast of spore-pollen quantitative analysis and deposits-indicator qualitative analysis.
