| Abstract: | Through field survey, with geological and geomorpohologic methods and dating the fault gouge and Quaternary sediments, we made certain study on tectonic deformation and activity of the middle segment of Baihe Gucheng fault. Some conclusions can be drawn that the fault belt suffered from multi stage tectonic deformation and it is clearly zoning. The lifting velocity of fault and its neighbouring area ranges from 0.64
mma -1 to 0.85 mma-1 since the Middle stage of Late Pleistocene. The fault was predominantly active in the Early Quaternary with sinistral slip component. The seismicity of fault and nearby tends to enhance in time domain and is tectonically relatated to the fault in spatial domain. |
