| 摘 要： | 通过观测、统计太仆寺旗地区不同岩性地层中节理的产状、性质及彼此相互切割的特征,用构造解析法对观测的节理进行分期配套,选出多组共轭节理,并通过投图分析计算出各组共轭节理的最大主应力值(σ_1)、中间应力值(σ_2)和最小应力值(σ_3),在太仆寺旗地区内恢复了3期构造应力。结合区域资料及野外观测数据分析,将区域构造演化划分为5个阶段。

| Abstract: | On the basis of observation and statistics of occurrence,property and cutting relation of joints in different lithologic stratum in Taipusiqi area,Inner Mongolia the authors divided formation stages of the joints and fit the joints in systems.Multi-groups of conjugate joints are picked up.Projection of joint occurrence was used to calculate maximum principal stress value (σ1),medium value (σ2) and minimum value (σ3).Three stages of structural stress are reconstructed in Taipusiqi area.5 stage division of regional structural evolution is based on the collection of regional data and analysis of the field observation data. |

| Keywords: | Taipusiqi area conjugate joints structural stress field structural evolution Inner Mongolia |
