摘　　要：详细列出松辽盆地南部泉头组主要孢粉组合及百分含量。泉头组的孢粉组合带反映了新老交替的特点,被子植物花粉开始发展,一部分早白垩世常见分子有的绝灭,有的衰退。综合考虑泉头组的时代应为阿尔必中晚期。This paper mainly lists sporopollen assemblages and percentage of Quantou Formation in the Southern Songliao Basin. Sporopollen assemblages and percentage of Quantou Formation reflects the characteristics of the succession of new and old, angiosperm pollen starts to develop, partly of members often seen in the Early Cretaceous flora become extinct or recession. The study of above sporopollen assemblages has demonstrated that the geologic age of Quantou Formation belongs to metaphase and later period of Albian.
