| Abstract: | The process and result of fractal research of natural fault gouge collected from the active fault zone at northern edge of
Western Qinling Mt. by using optical and electronic microscope technics were introduced in this paper. The fractal dimension
of this fault gouge isD=2.594±0.122 (2 D planeD=1.594±0.122), and its upper limit of fractal dimension occurs at grain size at 9.6–19.2 mm. The study result shows that this
gouge is fractal, and its characteristic displacement parameter of stick-slip friction can be determined by upper limit of
fractal dimension. The feature of protolith which affect fractality and the significance of gouge fractal to seismic fault
changes are also discussed in the paper.
