| 摘 要： | 对包头平原第四纪堆积物的年代地层、生物地层、岩石地层和磁性地层的研究表明,该区晚更新世—全新世地层可与我国华北晚更新世—全新世典型地层剖面——萨拉乌苏河滴哨沟湾剖面对比,并可进一步划分出萨拉乌苏组、城川组、大沟湾组和滴哨沟湾组。这一研究不仅重新厘定了包头平原这一时段地层的层序,完成大区域地层对比,同时也为研究包头地区乃至呼包盆地晚更新世—全新世古气候和古地理环境变迁提供了基础资料。

| Abstract: | Chronostratigraphic, biostratigraphic, lithostratigraphic, and magnetostratigraphic investigation of the Neogene sediments of the Baotou Plain suggests that the late Pleistocene—Holocene strata may be correlated with the Dishaogouwan profile at the Salawusu River, a Pleistocene—Holocene type section in North China. The strata can be further subdivided into the Salawusu Formation, Chengchuan Formation, Dagouwan Formation, and Dishaogouwan Formation. The study not only revises the Neogene stratigraphy in the Baotou Plain, which facilitates regional stratigraphic correlation, but also provides stratigraphic data for the study of Neogene paleoclimatic and paleogeographic changes in the Baotou area and the Hubao Basin. |
