摘要
笔者对研究区露头上的小褶皱进行了详细观测后认为：该区存在三期叠加褶皱；借助褶皱不同部位上的岩组分析，可以从微观上验证叠加褶皱的次数；通过叠加褶皱及其岩组分析，有助于恢复区域构造样式、划分地层及判断构造环境。
On the basis of detailed observation of the small folds at the outcrops in the studied re-gion,we think that three-period superimposed folds exist in this area.By means of petrofabric analysisof the different parts of folds,it is possible to test the times of the superimposed folds in microcos-mic.The study of superimposed folds and analysis of petrofabrics are helpful for the reappearance ofregional structural pattern,the division of strata and the determination of tectonic environment.
