| 中文摘要:通过大量断层擦痕数据计算机处理和野外地质观察，作者将青藏高原北缘上新世以来的脆性构造应力场分为２期；上新世－中更新世，主压应力近于Ｓ－Ｎ；中更新世至今，主压应力方位为ＮＥ向和ＮＷ向；最后对青藏高原北缘的地球动力学过程作了分析。 |

| A Study on Tectonic Stress's Field of Brittle Deformation in the Northern Tibet Qinghai Plateau |

|
| Abstract:Through field observation and computer processing of fault slip data, we divided the brittle tectonic stress' fields in the northern Tibet Qinghai plateau into two periods: Oligocene middle Pleistocene and middle Pleistocene Holocene. The maximum principal stress's orientation is approximately S N direction in the former period and N E in Altyn Taph and N W in Qilian respectively in the latter one. Meanwhile, geodyncmics of the northern Tibet Qinghai plateau is analysized. |
