摘要
从地质、地貌、地球化学、地壳形变、地震活动等多学科研究分析深圳市断裂第四纪以来的活动 ,指出晚更新世以前北东向与北西向两组断裂有多期活动 ,并以后者切截 ,错移前者为特征。但晚更新世以来至今活动已明显减弱 ,现今活动微弱。断裂活动对该地区地壳稳定性及其他地质地貌环境没有构成较严重的自然灾害隐患。
Fault activities since Quaternary period in Shenzhen City are discussed according to the study of Quaternary geology, geomorphology, geochemistry, crustal deformation and seismology. Before late-Pleistocene NE and NW trend faults activated repeatedly, when NW trend fault cut off and staggered NE trend fault. But since late Pleistocene their activities weakened. At present, fault activities in Shenzhen are weak, and do not have great influence on crust stability and geologic environment. There is less possibility to cause serious geologic disasters in the city.
