| 摘 要： | 沿阿尔金断裂带东南侧发育六个中、新生代的含油气盆地，盆地的边缘或盆地内部发育一系列的近东西走向、与阿尔金断裂锐角相交的断裂，该组断裂对盆地的隆坳格局和地层分布具有控制作用，盆地具有箕状结构或不对称结构特点。沿阿尔金断裂带方向，保罗系、白垩系、古近系、新近系的厚度和沉积特征在时空上呈有规律性变化，显示了阿尔金断裂带时、空活动的差异性。根据侏罗纪盆地在阿尔金断裂带两侧的展布特征和柴达木盆地西部发育的鼻状构造及其沉积演化特征，推断阿尔金断裂带中、新生代经历了多期不同方向的走滑运动。

| Abstract: | Six petroliferous basins are developed on the southeast side of the Altun fault belt, and a group of EW-trending faults are developed in the basins or on the edges of the basins, which intersect the Altun fault belt with acute angles. These faults control the pattern of basins and the distribution of strata. The basins have half-faulted or asymmetrical structures. Thickness and features of the Jurassic, Cretaceous, Paleogene and Neogene sediments in basins change regularly along the Altun fault belt. These regularities indicate different activities of the Altun fault belt in space and time. According to structural characteristics of the Jurassic basins on both sides of the Altun fault belt, the faulted noses and their sedimentary evolution in the west of the Qaidam basin, it is inferred that the alternation between dextral and sinistral movements of the Altun fault belt has occurred several times in the Mesozoic and Cenozoic. |
