| 摘 要： | 在分析研究青藏高原东北缘地震、地震形变带及活动断裂带的基础上,确定了NNW向最新活动构造体系。该体系的主体构造是由一系列呈NNW向相间展布的现代隆起带和沉降带组成。青藏高原东北缘最新构造变形是该构造体系活动的结果。另外,还对体系的变形特征及"敏感点"进行了较详细的探讨。 |
| 关 键 词： | 地震形变带 活动断裂 活动构造体系 最新构造变形 |

| Abstract: | A recently active tectonic system which strikes NNW is determined by analyzing and Studying the earthquakes, seismic deformation bands and active fault zones along the northeastern margin of the Qinghai-Tibetan Plateau. It consists mainly of a series of modern uplifts alternating with sudsidence zones. The latest tectonic deformation along the north-eastern margin of the plateau was found to have resulted from the activity of the system. In addition, a more detailed discussion of the deformation of the system and the earthquake-prone areas is made. |
| Keywords: | seismic deformation hands active fault active tectonic system recently tectonic formation |
