| 摘 要： | 在内蒙古固阳县以东下湿壕地区 1∶5万区域地质调查中 ,首次在前人划分的下白垩统固阳组 采到瓣腮类、腹足类、介形类、轮藻、植物等大量化石。结合地层沉积组合特征 ,将原固阳组重新厘定为下白垩统李三沟组。这一地层层位的厘定和古生物化石的发现 ,对进一步探讨固阳盆地的构造演化和成煤规律等都将具有重要的理论意义和实际价值

| Abstract: | During
1∶50 000 regional survey in the Xiashihao area east of Guyang county,Inner Mongolia,the
authors first collected abundant fossils of pelecypods,gastropods,ostrocods,charophytes
and embryophytes in the Lower Cretaceous Guyang Formation determined previously.According
to the fossils combined with the features of sediment associations,the original Guyang
Formation is revised and renamed the Lower Cretaceous Lisangou Formation. |
