| 摘 要： | 早石炭世构造层次（C1）的地层发生了强烈的挤压变形,有较为紧闭的背、向斜构造和复杂的层间褶曲发育,局部见尖棱状褶曲。晚石炭世构造层（C2）包括上石炭统希贝库拉斯组、太勒古拉组地层挤压变形比较弱,形成比较宽缓的褶皱。二者间明显分属不同的构造变形层次,反映了早石炭世末研究区曾发生过一次重大的运动,这一结论,不仅澄清了多年来...

| Abstract: | The stratum of Early Carboniferous structural level（C1） occurred strongly compressive deformation,there are closed anticline and syncline and complexity inter-layer fold,in addition,the sharp edges-like fold exist locally.Late Carboniferous structural layer（C2） includes the Upper Carboniferous Xibeikulasi Formation and Tailegula Formation.Obviously the two formations belong to different tectonic deformation levels,which represent the extension of a major movement at the end of Early Carboniferous.It has great significance for clarifying the sequence relationship between Xibeikulasi Formation and Tailegula Formation which have debated for many years,also providing the latest information to study the tectonic evolution of West Junggar. |
