| 摘 要： | 阿尔金断裂带东延区与北祁连冲断带一起控制了酒泉盆地的形成和演化.作者利用区域地球物理资料的解释和分析,研究了阿尔金断裂走滑过程对酒泉盆地的控制作用和影响范围,认为阿尔金断裂走滑运动始于中生代白垩纪,初次隆升始于白垩纪,不晚于古新世;其东延应止于花海凹陷.阿尔金断裂带对酒泉盆地的控制作用主要表现为限制了盆地现今的西部边界,同时控制了盆地北段的构造形态.

| Abstract: | The eastern extension of Altyn Fault and the Qilian thrusting belt controlled the formation and evolution of Jiuquan Basin. This paper studies the function and range of the controlling of the Altyn Fault upon Jiuquan Basin, based on the interpretation and analysis of regional geophysical data. Our results indicate the movement and uplift of the Altyn Fault started in the Cretaceous, predating the Paleocene, and its eastern extension is considered to be limited within Huahai depression. The Altyn Fault defined the western boundary of Jiuquan Basin and controlled the structural features of its northern portion. |
