| 摘 要： | 文中采用遥感资料,对阿尔泰山东缘的主要活动断裂———科布多(Hovd)断裂与哈尔乌苏湖(Har-Nuur)断裂进行研究,从地貌特征上对断裂进行详细分析,揭示其几何学和运动学特征。初步研究表明阿尔泰山东缘的活动断裂规模、滑动速率和强地震活动并不弱于其西南缘。其中科布多断裂走向NNW,右旋走滑,长约600km,中更新世(Q2p)以来最大水系右旋位错约9.0km,滑动速率可达3.8～12.3mm/a,平均滑动速率约7.8mm/a;哈尔乌苏湖断裂走向NNW,右旋走滑,长约480km,全新世以来活动性明显增强,第四纪洪积扇上发现有最新的断裂迹象。阿尔泰山东缘的新构造运动与强地震活动,除了与印度-欧亚板块碰撞作用有关外,可能还与局部地区的动力学过程有关 |

| Abstract: | Using remote sensing (RS) data, the major active faults of the eastern margin of Altai Mountains——the Hovd Fault and the Har-Nuur Fault, are studied, the detailed rupture character is analyzed from a viewpoint of topographic features, and the fault geometry and kinematics characteristics are revealed. Preliminary researches indicate the scale, slip-rate and strong seismic activity of active faults along the eastern margin of Altai Mountains are not weaker than those of the southwest s. The Hovd Fault is of |
