阿尔金断裂带走滑速率的研究长期以来一直是地质学家关注的焦点。但现有的研究集中在阿尔金断裂带的中段和东段呢，而在断裂带中段与西段连接过渡带的阿什库勒段的研究还是一片空白。在前期的工作基础上，本项目拟在阿什库勒地区开展活动构造研究，通过阿什库勒断裂切割不同级河流阶地位移量的精确测量和各级阶地面年龄的测定，确定阿尔金断裂带阿什库勒段晚第四纪以来的左旋走滑速率，全面认识阿尔金断裂的走滑作用，为青藏高原大陆变形模型提供基础依据；同时根据阶地的形态和沉积特征及阶地面形成年龄，探讨该地区的隆升时代的，并结合阶地隆升高度，确定阿什库勒地区晚第四纪以来的隆升速率；在此基础上，确定阿什库勒地区断裂走滑速率与区域隆升速率的分配，进一步根据与邻区断裂规模和变形量的对比，确定阿什库勒断裂在阿尔金断裂带过渡带变形中所占的比例，建立阿什库勒地区变形作用模型。

Study on the slip rate along the Altyn Tagh fault had been a long-term focus for geologists. Many works had been done in the central and east segment of the Altyn Tagh fault, whereas slip rate on the Ashikule segment, which located in the transition zone between the central segment and the west segment of the Altyn Tagh fault, is still unknown. Based on our former study, this new project intend to study active tectonics in the Ashikule area. By measuring the terraces offsets which were cut by the Ashikule fault, and dating of terrace surfaces, we are going to constrain the Late Quaternary slip rates along the Ashikule segment of the Altyn Tagh fault, which can help us better understanding the strike-slipping of the Altyn Tagh fault, and provide basis for the continental deformation model of the Tibetan Plateau. Late Quaternary uplift rate will also be constrained in this area, by distinguishing tectonic origin terraces from their morphological and sedimentary characteristics, determining the time of uplift, and measuring the height of uplift. Partitioning between strike-slip and uplift can be determined then. By comparing the scale and deformation of the Ashikule fault and other faults in this area, the final goal of the project is to determine the role that the Ashikule fault has played in the transition zone of the Altyn Tagh fault, and set up a deformation model of the Ashikule area.
