Abstract: Geological and structural features from Archaean to neotectonics along the Geosci-ence Transect corridor from Baotou to Mandula have been accounted. Particular attention has been paid to the middle Proterozoic Chartai aulacogen and Bayan Obo geocline. Both of them were folded during the Seerteng movement about 1400 Ma ago and became the latest consolidated part of the North China platform basement. The Caledonian and Variscan fold belts of the northern marginal tracts have also been discussed

Key words: Geoscience transect, Aulacogen, Geocline

摘要： 本文概述了江苏响水至内蒙古满都拉地学断面北段——包头至满都拉的地质观察结果。内容包括从太古宙乌拉山群到第四系、基底构造到新构造特征的七个方面。重点论述了渣尔泰群和白云鄂博群的构造性质,它们约在14亿年前才褶皱回返,代表了华北地台基底固结最迟的地段。造成这一事件的构造运动,拟称为色尔腾运动。此外,还讨论了华北地台北侧陆缘区加里东期和华力西期的构造。
