1957年我们在甘肃永昌、山丹以北的潮水盆地进行石油地质研究的时候,发现作为阿拉善三角地(陆台)南部凹陷地带的潮水盆地的新构造运动还显得异常活跃。因此,我们曾对这些现象加以注意。自1940年以来,盆地的地质构造曾历经我国许多地质学家的调查研究,但关于盆地的新构造运动几乎未见报导。直到最近才出现了有关本区青土井一带冲积扇的发育及阶地等现象。以及对第四纪断裂、隆
In 1957, when we conducted petroleum geology research in Yongchang, Gansu, and the tidal basin north of Shandan, we found that the neotectonic movement of the tidal basin, which is the southern depression of the Alashan Triangle (Lutai), is still very active. Therefore, we have paid attention to these phenomena. Since 1940, the geological structure of the basin has been investigated by many geologists in our country, but few neotectonic movements have been reported in the basin. Until recently, there emerged the development of alluvial fans in the Qingtujing area in this area and the terraces. And the Quaternary fault, Long
