| 中文摘要:红河断裂带(RRFZ)是一条大型的走滑断裂带,本文利用1999年和2003年的GPS观测,通过数据反演,获得在欧亚参考框架下的速度矢量图。结果表明:在欧亚框架下,东向分量平均速度为3.726mm/a;北向分量平均速度为-9.013mm/a;由北向南,各测站的北向分量速率值逐渐减小;由西向东,各测站的东向分量速率值逐渐减小;测区内呈现明显的右旋拉张走滑运动。分析表明云南红河地区地壳水平运动的特征以及断裂活动性质与构造地质相当一致。 |

| Abstract:The Red River fault zone is a gigantic sliding fault zone. On the basis of GPS observations in Yunnan in 1999 and 2003, the velocity vector diagram was drawn against the Eurasia reference framework. The average velocity is 3.726 mm/a in east direction and-9.013 mm/a in north direction. The velocity component of the GPS stations in the north is reduced from north to south, and that in the east is reduced from west to east. In the surveying zone, the GPS stations show obvious extensional and right_lateral strike_slip movement. An analysis of the features of the horizontal movement in the Red River zone reveals that the faulting activity characteristics are quite consistent with geological results. |
