广东省五华-深圳断裂带、以几条近于平行的断裂构成一个规模较大的变形带通过深圳特区,对特区建设具有一定影响。本文从断裂带空间延伸、结构形态的宏观调查,结合断裂带的岩石组构分析、岩石有限应变测量和古应力值估算等方面资料,对断裂带的变形强弱趋势,变形方式,演化规律作了探讨,为深圳市地壳构造稳定性评价提供了地质判据。关键词:构造体系地应力场糜棱岩碎裂岩组构分析应变测量固态流变地质应力计自由位错密度动态重结晶差异应力
The Wuhua-Shenzhen fault zone in Guangdong Province formed a large deformation zone near the parallel faults through the Shenzhen Special Economic Zone with a certain impact on the construction of the SAR. In this paper, based on the macro-investigation of the spatial extension of the fault zone, the structural morphology of the fault zone, the analysis of the rock structure of the fault zone, the finite strain measurement of the rock and the evaluation of the paleo-stress value, the trend of deformation and deformation, the deformation mode and the evolution law The discussion provided a geological criterion for the evaluation of crustal structural stability in Shenzhen.
