| 摘 要： | 利用遥感资料 ,通过野外实地考察并结合气候地貌事件的分析 ,对斜切北天山、长逾70 0km的博阿断裂 (博罗科努 -阿齐克库都克断裂 )的右旋走滑运动进行了定量研究。该断裂分为西部NW向断裂和东部NWW向断裂。西部NW向断裂长近 2 5 0km ,向西北延伸进入哈萨克斯坦 ,右旋走滑速率可达 5mm/a ;由 4～ 5个断裂段组成 ,其上发育 3～ 4条古地震或历史地震形变带 ,显示具有发生 7.5级地震的能力。东部NWW向断裂右旋走滑速率 1～ 1.4mm/a ;其上发现小规模古地震形变带 ,显示具备发生 7级左右地震的能力。该断裂与山前的逆冲推覆构造之间构成典型的挤压区应变分配形式 ,即在斜向挤压作用下 ,变形分配为山前的逆冲推覆构造和山内的走滑断裂 |
| 关 键 词： | 走滑断裂 博阿断裂 应变分配 活动构造 地震形变带 天山 |

| Abstract: | The Bolokenu Aqikekuduke Fault extends over 700km and obliquely cuts the North Tian Shan. The fault is quantitatively studied in this paper based on remote sensing data, field observation, and the analyses of the relationship between the morphology and the climate change. The fault is composed of two portions, the NW striking western portion and the NWW striking eastern portion. The western portion is right lateral strike slip with a rate of 5mm/a, having a length of about 250km and extending northwest |
| Keywords: | strike slip fault Bolokenu Aqikekuduke Fault strain partitioning earthquake deformation zone active fault Tian Shan |
