张家口—渤海断裂带分段运动变形特征分析

Abstract

Abstract: With collected GPS data in the period of 1999~2007 from the Crustal Motion Observation Network of China along the Zhangjiakou-Bohai fault and its adjacent regions,we study the characteristics of present-day crustal horizontal motion velocities in the research zone. Strain rate components are computed in spheric coordinate system with the least square collocation method. According to the spatial distribution of the principal strain rate, dilation rate and maximum shear strain rate derived from GPS measurements, we analyse the deformation of the subordinary faults of the Zhangjiakou-Bohai fault. The principal compression strain rates are apparently greater than principal extension strain rates. The larger shear strain rates mainly distribute in and around the areas of Xianghe, Wenan, and Tangshan in Hebei Province. According to the profiles across different segments of the Zhangjiakou-Bohai fault, the three segments along the Zhangjiakou-Bohai fault show an obviously left-lateal strike slip and compression characteristics. By analysing the motion characteristics of the blocks,Yanshan block, North China Plain block, Ordos block, and Ludong-Huanghai block in and around the North China, we spectulate that the dynamics of the motion styles of Zhangjiakou-Bohai fault may directly come from the relative movement between the Yanshan block and the North China plain block, and the ultimately dynamics may be the results of the collison between Indian plate and Eurasian plate, and the persistent northeastward movement of the Indian plate.

Key words: Crustal deformation, Velocity filed, Strain rate filed, Zhangjiakou-Bohai fault zone
