The fractal feature of granulometric composition in fault gouges from the Yishu fault zone and adjacent northwest-trending faults and its seismo-geological implications

摘要

In this work, the fractal dimension of granulometric composition in the fault gouge from the Yishu fault zone and northwest-trending faults on its west side is calculated and studied based on the fractal theory of rock fragmentation. The seismo-geological implications of the fractal dimension of granulometric composition in fault gouges are also discussed. The results show that the Yishu fault zone is more active than the northwest-trending faults and the Anqiu-Juzian fault is the most active in the Yishu fault zone.
