| 中文摘要: |
| 乌拉特中旗赛音呼都格地区渣尔泰群经历了两期构造变形:早期(主期)褶皱样式为不协调褶皱,发育大型的同斜褶皱,构造应力场方向为NWW-SEE向;晚期褶皱以宽缓弯曲的形式,横跨叠加在主期褶皱之上,主要表现为轴面面理在走向和倾向上的波状弯曲,区域主压应力为近EW向。 |
| 英文摘要: |
| Two stages of tectonic deformation occurred at Chartai group in Sain Hudag, Urad Zhongqi. The first stage is characterized by disharmonic folding and large isoclinal fold was developed under NWW-SEE stress field. The second stage is characterized by gentle open fold with wavy curve foliation along both the strike and dip and overprinting of fold of the second stage on that of the first stage and the principle stress is nearly in EW direction. |
