| 摘 要： | 新的证据显示,位于祁连山西段酒西盆地南部的玉门断裂的最新活动时代为晚更新世末,并兼有一定的走滑分量.这一结果表明,酒西盆地块体周边断裂的活动具有同时性的特点,酒西盆地块体可能发生过顺时针旋转.

| Abstract: | Field investigation reveals that the latest time when Yumen fault,western part of Qilian Mountains was active is the end of the late Pleistocene,and that the fault is coincident with other faults around west Jiuquan basin.It is also found that Yumen fault had not simply restricted to dip slip motion,strike slip motion is indicated.The results suggest that west Jiuquan basin block might have rotated clockwise. |
